Mohammed Shawqui Islambouli.Mohammed Shawqui Islambouli. [Source: Public domain]On December 4, 1998, an item in President Clinton’s Presidential Daily Briefing (PDB) is titled, “Bin Laden Preparing to Hijack US Aircraft and Other Attacks.” The PDB says “Bin Laden and is allies are preparing for attacks in the US, including an aircraft hijacking to obtain the release of Sheikh Omar Abdul-Rahman, Ramzi Yousef, and Muhammad Sadiq ‘Awda. One source quoted a senior member of Al-Gama’a al-Islamiyya (IG) saying that, as of late October, the IG had completed planning for an operation in the US on behalf of bin Laden, but that the operation was on hold. A senior bin Laden operative from Saudi Arabia was to visit IG counterparts in the US soon thereafter to discuss options-perhaps including an aircraft hijacking.” The same source says bin Laden may implement plans to hijack US aircraft before the start of the Muslim holy month of Ramadan on December 20 and that two members of the operational team had evaded security checks in a recent trial run at a New York airport. A possible different source says that in late September, Mohammed Shawqui Islambouli, brother of the assassin of Egyptian President Anwar Sadat and described in the PDB as an IG leader, was planning to hijack a US airliner during the “next couple of weeks” to free Abdul-Rahman and other prisoners. The PDB also says that “some members of the bin Laden network have received hijack training, according to various sources, but no group directly tied to bin Laden’s al-Qaeda organization has ever carried out an aircraft hijacking. Bin Laden could be weighing other types of operations against US aircraft.” The PDB mentions other bin Laden related threats, including recent reports that the IG has obtained surface-to-air missiles and intends to move them from Yemen to Saudi Arabia to shoot down aircraft. [Washington Post, 7/18/2004; 9/11 Commission, 7/24/2004, pp. 128-130] The private intelligence group Stratfor will later say that, in addition to his ties with IG, Islambouli worked with bin Laden in the Maktab al-Khidamat charity front in Pakistan and is believed to have lived in Afghanistan in the 1990s as “part of the group of key Egyptian advisers surrounding bin Laden.” Islambouli will formally join with al-Qaeda in 2006. [Stratfor, 8/10/2006] In early 1998, the CIA ignored information from a recently retired CIA agent that claimed 9/11 mastermind Khalid Shaikh Mohammed was in a terrorist cell with Islambouli, both were experts on plane hijackings, and were planning to hijack planes (see Early 1998). Perhaps not coincidentally, on this same day, CIA Director George Tenet issues a “declaration of war” against al-Qaeda in a memo to the US intelligence community (see December 4, 1998). Also on this day, counterterrorism “tsar” Richard Clarke holds a meeting of his interagency Counterterrorism and Security Group (CSG) to discuss the threat. The group agrees that New York City airports should go on a maximum security alert that weekend and security should be boosted at other East Coast airports. The FBI, FAA, and New York City Police Department get versions of the PDB report. Later in December and again in January 1999 the source says the hijacking has been postponed because two operatives have been arrested in Washington or New York. But the FBI is unable to find any information to support the threat nor is it able to verify any arrests similar to what the source described, and the source remains mysterious. The high alert in New York airports is canceled by the end of January. [9/11 Commission, 7/24/2004, pp. 128-130] This PDB will be mentioned in President Bush’s famous August 6, 2001 PDB, but mentions that US officials “have not been able to corroborate” the plot (see August 6, 2001).

As an al-Qaeda millennium plot is broken up in Jordan (see November 30, 1999), attention is focused on the fact that two of the plotters were long time US residents. National Security Adviser Sandy Berger sends a memo to President Clinton about the two men, Raed Hijazi and Khalil Deek. Hijazi had lived in California and then moved to Boston to drive a taxi there for several years. The 9/11 Commission will say Berger tells Clinton was a naturalized US citizen who had “been in touch with extremists in the United States as well as abroad.” Later in the month, counterterrorism “tsar” Richard Clarke will warn Berger in an e-mail, “Foreign terrorist sleeper cells are present in the US and attacks in the US are likely.” [9/11 Commission, 7/24/2004, pp. 179, 501] Deek is arrested on December 11 (see December 11, 1999), but he will eventually be released without being charged (see May 2001). A few days later, Clarke authorizes a study that looks into Deek’s connections, but no action will be taken when it is discovered Deek’s next-door neighbor is still living in Anaheim, California, and running an al-Qaeda sleeper cell there (see December 14-25, 1999). Similarly, while Hijazi will be arrested overseas some months later (see September 2000), US intelligence seems oblivious to the other al-Qaeda operatives who have been his roommates and fellow taxi drivers in Boston (see June 1995-Early 1999 and October 2000). One of them, Nabil al-Marabh, will apparently go on to have a major role in the 9/11 plot (see for example January 2001-Summer 2001 and Early September 2001). Investigators will also fail to act on knowledge of financial transactions between Hijazi and three of the 9/11 hijackers (see Spring 2001).

In the wake of disrupting Ahmed Ressam’s millennium bomb plot at the end of 1999 and arresting his cohorts (see December 14, 1999) (see December 15-31, 1999), US intelligence remains concerned that al-Qaeda sleeper cells remain in the US (see March 10, 2000). However, Clinton’s National Security Adviser Sandy Berger later claims that the FBI still repeatedly assures the Clinton White House that al-Qaeda lacks the ability to launch a domestic strike. [New York Times, 9/22/2002] He says, “Until the very end of our time in office, the view we received from the [FBI] was that al-Qaeda had limited capacity to operate in the US and any presence here was under surveillance.” No analysis is done before 9/11 to investigate just how big that presence might be.

In a memo to President Clinton that is also widely distributed in the US intelligence community, CIA Director George Tenet warns: “The next several weeks will bring an increased risk of attacks on our country’s interests from one or more Middle Eastern terrorist groups… The volume of credible threat reporting has grown significantly in the past few months, particularly concerning plans by Osama bin Laden’s organization for new attacks in Europe and the Middle East.… Our most credible information on bin Laden activity suggests his organization is looking at US facilities in the Middle East, especially the Arabian peninsula, in Turkey and Western Europe. Bin Laden’s network is global however and capable of attacks in other regions, including the United States.” [Tenet, 2007, pp. 128-129] Just one day later, Clinton will brief incoming President Bush on the al-Qaeda threat (see December 19, 2000).

Clinton and Bush meeting in the White House on December 19, 2000.Clinton and Bush meeting in the White House on December 19, 2000. [Source: NBC]President Clinton and President-Elect Bush meet for their "exit interview," in a two-hour meeting. [CNN, 12/19/2000] Clinton gives Bush his list of his top five priorities. At the top of the list is dealing with Osama bin Laden. Clinton also discusses the tensions between Pakistan and India, who are threatening each other with nuclear strikes; the crisis in the Middle East between Israel and Palestine; he discusses North Korea; and he discusses Iraq and Saddam Hussein. Bush shakes Clinton’s hand after Clinton wraps up his presentation, and says, "Thanks for your advice, Mr. President, but I think you’ve got your priorities wrong. I’m putting Saddam at the top of the list." [Moore, 3/15/2004, pp. 16-17] Just one day before, CIA Director George Tenet had warned Clinton that al-Qaeda could attack US interests in the next several weeks (see December 18, 2000). In 2003, Clinton will speak about the interview, saying that he recognized Bush felt the biggest security issues facing the US was Iraq and a national missile defense: "I told him that in my opinion, the biggest security problem was Osama bin Laden."

National Security Adviser Condoleezza Rice later testifies to the 9/11 Commission that in the first eight months of Bush’s presidency before 9/11, “the president receive[s] at these [Presidential Daily Briefings] more than 40 briefing items on al-Qaeda, and 13 of those [are] in response to questions he or his top advisers posed.” [Washington Post, 4/8/2004] The content of the warnings in these briefings are unknown. However, CIA Director George Tenet claims that none of the warnings specifically indicates terrorists plan to fly hijacked commercial aircraft into buildings in the US. [New York Times, 4/4/2004] Counterterrorism “tsar” Richard Clarke will later emphasize, “Tenet on 40 occasions in… morning meetings mentioned al-Qaeda to the president. Forty times, many of them in a very alarmed way, about a pending attack.” [Vanity Fair, 11/2004] These briefings are normally given in person by CIA Director George Tenet, and are usually attended by Vice President Cheney and National Security Adviser Rice. In the Clinton administration, up to 25 officials recieved the PDB. But in the Bush adminisration before 9/11, this was sharply reduced to only six people (see After January 20, 2001). Other top officials have to make due with an Senior Executive Intelligence Brief generally released one day later, which is similar to the PDB but often contains less information (see August 7, 2001).

Counterterrorism “tsar” Richard Clarke submits a comprehensive plan to deal with al-Qaeda within days of President Bush’s inauguration (see January 25, 2001). He wants to meet with Bush directly to discuss it with him, but he is unable to do so before 9/11. Clarke will later recall, “I asked for a meeting with the president several times beginning, in fact, before [National Security Adviser] Rice even took office in the transition briefing. I said I have given this briefing to the vice president, I’ve given it to the secretary of state, I’ve given it now to you, I would like to give it to the president. And what I was told was I could brief the president on terrorism after the policy development process had been completed.” He does have one meeting with Bush before 9/11, but only to discuss cyber security because Clarke is planning to quit his current job to focus on that issue instead (see June 2001). When asked why he didn’t bring up al-Qaeda at that meeting, Clarke will reply, “Because I had been told by Dr. Rice and her deputy that this was a briefing on countering the cyber threats and not on al-Qaeda and that I would have my opportunity on al-Qaeda if I just held on, eventually they would get to it, probably in September.” [ABC News, 4/8/2004] The Bush administration had downgraded Clarke’s position in early January 2001 and he was no longer able to send memos directly to the president as he could during the Clinton administration (see January 3, 2001).

Counterterrorism “tsar” Richard Clarke briefs Vice President Cheney about the al-Qaeda threat. He urges decisive and quick action against al-Qaeda. Cheney soon visits CIA headquarters for more information about al-Qaeda. However, at later high-level meetings Cheney fails to bring up al-Qaeda as a priority issue.

A Senior Executive Intelligence Brief (SEIB), entitled “Sunni Terrorist Threat Growing,” is sent to top White House officials. It indicates a heightened threat of Sunni extremist attacks, particularly in the Middle East and Europe, against US facilities and personnel. (Bin Laden is the most wanted Sunni extremist by this time.) The briefing states this is considered the most significant spike in threat reporting since the Millennium. The SEIB is usually released one day after the corresponding President Daily Briefing is given to the president and contains similar content (see January 20-September 10, 2001), so it is probable Bush is given this warning. Based on this warning, a terrorist threat advisory will be shared throughout the US intelligence community on March 30, and the FBI will send out a warning to its field offices in April (see April 13, 2001).

On April 19, 2001, the interagency Counterterrorism Security Group (CSG) chaired by counterterrorism “tsar” Richard Clarke discusses recent reports that al-Qaeda leader Abu Zubaida is planning an attack. The next day, a Senior Executive Intelligence Brief (SEIB) with the title “Bin Laden Planning Multiple Operations” is sent to top White House officials. The New York Times will later report that President Bush and Vice President Cheney were among those who received this warning. Since SEIBs are usually based on previous days’ President Daily Briefings, President Bush probably learned about this report on April 19 (see January 20-September 10, 2001).

A Senior Executive Intelligence Brief (SEIB) about Osama bin Laden sent to top White House officials on May 3, 2001, is entitled, “Bin Laden Public Profile May Presage Attack.” Apparently it suggests that recent public comments by bin Laden could be hinting at future attacks, but details of what exactly he said or did to cause this warning have not be made public. The New York Times will later report that President Bush and Vice President Cheney were among those who received this warning. Since SEIBs are typically based on the previous day’s President Daily Briefings (see January 20-September 10, 2001), President Bush was probably informed about this warning on May 2.

A Senior Executive Intelligence Brief (SEIB) sent to top White House officials is entitled, “Terrorist Groups Said Cooperating on US Hostage Plot.” It warns of a possible hostage plot against the US abroad to force to release of prisoners being held in the US, including Sheikh Omar Abdul-Rahman (see July 1990). The report notes operatives might hijack an aircraft or storm a US embassy overseas. SEIBs are typically based on the previous day’s President Daily Briefing (see January 20-September 10, 2001), so it is probable President Bush is given this information.

According to a 2006 book by journalist Bob Woodward, in the months before 9/11, CIA Director Tenet believes that Defense Secretary Rumsfeld is impeding the effort to develop a coherent strategy to capture or kill bin Laden. Rumsfeld questions al-Qaeda communications intercepts by the NSA and other other intelligence. [New York Times, 9/29/2006] Woodward writes in his book, “Could all this be a grand deception? Rumsfeld had asked. Perhaps it was a plan to measure US reactions and defenses. Tenet had the NSA review all the intercepts, and the agency concluded they were of genuine al-Qaeda communications.” As a result of these doubts, on June 30, 2001, a Senior Executive Intelligence Brief (SEIB) sent to top White House officials contains an article entitled, “Bin Laden Threats Are Real” (see June 30, 2001). [Woodward, 2006, pp. 50] However, apparently this does not quell the doubts. For instance, in mid-July 2001, Tenet is told that Deputy Defense Secretary and close Rumsfeld ally Paul Wolfowitz still doubts the surge of warnings and suggests that bin Laden may merely be trying to study US reactions to an attack threat (see Mid-July 2001).

The CIA tells President Bush that co-operation between the CIA and Saudi Arabia’s GID intelligence agency has enabled the US to penetrate al-Qaeda, according to a later account by investigative reporters Joe and Susan Trento. They will write: “The great secret of why the president and his team were complacent about warnings of an impending 9/11 attack in the summer of 2001 is that the CIA had assured the national command authority that the CIA’s cooperative arrangement with Saudi intelligence had resulted in the penetration of al-Qaeda at the highest levels, according to intelligence sources who worked in this area for both the Saudi and US services.” This may be a reference to 9/11 hijackers Nawaf Alhazmi and Khalid Almihdhar, who the Trentos claim are Saudi intelligence agents (see August 6, 2003).

A Senior Executive Intelligence Brief (SEIB) with the title “Bin Laden Attacks May Be Imminent” is sent to top White House officials. The details of this brief are not known. It is probable President Bush received this warning since SEIBs are usually rehashes of the previous days’ President Daily Briefing (see January 20-September 10, 2001). Also on this day a CIA cable is distributed with the title, “Possible Threat of Imminent Attack from Sunni Extremists.” The cable warns that there is a high probability of near-term “spectacular” terrorist attacks resulting in numerous casualties.

The briefing also contains another report entitled, “Bin Laden Threats Are Real.” SEIBs are typically based on the previous day’s President Daily Briefings (see January 20-September 10, 2001), so it is probable Bush is given this warning.

In 2002, Newsweek will report: “The White House acknowledged for the first time, [President] Bush was privately beginning to worry about the stream of terror warnings he was hearing that summer, most of them aimed at US targets abroad. On July 5, five days before the Phoenix memo (see July 10, 2001), Bush directed [Condoleezza] Rice to figure out what was going on domestically.” [Newsweek, 5/27/2002] In 2004, President Bush will explain why he requested this: “[T]he reason I did is because there had been a lot of threat intelligence from overseas. And part of it had to do with the Genoa [Italy] G8 conference that I was going to attend.” [US President, 4/19/2004] Though he does not mention it, the chief security concern at the late July 2001 conference he mentions is intelligence that al-Qaeda plans to fly an airplane into the conference. This threat is so widely reported before the conference (with some reports before July 5 (see June 13, 2001 and Mid-July 2001) that the attack is called off (see July 20-22, 2001). For instance, in late June, Time magazine mentioned a German intelligence report of an Osama bin Laden plot “to fly remote-controlled model aircraft packed with Semtex into the conference hall and blow the leaders of the industrialized world to smithereens” (see June 20, 2001). Bush will later claim that this request is specifically for the later-famous August 6, 2001 briefing entitled, “Bin Laden Determined to Strike in US” (see August 6, 2001), although the CIA analysts who draft it will deny this (see July 13, 2004).

By mid-July 2001, new intelligence indicates that the new al-Qaeda attack has been delayed, maybe for as long as two months, but not abandoned. So on this day, a Senior Executive Intelligence Brief (SEIB) sent to top White House officials is entitled, “Bin Laden Plans Delayed but Not Abandoned.” On July 25, a similar SEIB will be titled, “One Bin Laden Operation Delayed, Others Ongoing.” The SEIB is usually released one day after the corresponding President Daily Briefing and contains similar content (see January 20-September 10, 2001), so it is probable Bush receives this information. [9/11 Commission, 7/24/2004, pp. 259, 534] After 9/11, it will be discovered that in fact the 9/11 attack was originally planned to take place in the early summer but was delayed (see May-July 2001).

Advisors wait with classified briefings. [Source: White House]President Bush receives a classified presidential daily briefing (PDB) at his Crawford, Texas ranch indicating that Osama bin Laden might be planning to hijack commercial airliners. The PDB provided to him is entitled, “Bin Laden Determined to Strike in US.” The entire briefing focuses on the possibility of terrorist attacks inside the US. [New York Times, 5/15/2002; Newsweek, 5/27/2002] The analysts who drafted the briefing will say that they drafted it on the CIA’s initiative (see July 13, 2004), whereas in 2004 Bush will state that he requested a briefing on the topic due to threats relating to a conference in Genoa, Italy, in July 2001, where Western intelligence agencies believed Osama bin Laden was involved in a plot to crash an airplane into a building to kill Bush and other leaders (see April 13, 2004). The analysts will later explain that they saw it as an opportunity to convey that the threat of an al-Qaeda attack in the US was both current and serious. [9/11 Commission, 7/24/2004, pp. 260] The existence of this briefing is kept secret, until it is leaked in May 2002, causing a storm of controversy (see May 15, 2002). While National Security Adviser Condoleezza Rice will claim the memo is only one and a half pages long, other accounts state it is 11 1/2 pages instead of the usual two or three. [New York Times, 5/15/2002; Newsweek, 5/27/2002; Die Zeit (Hamburg), 10/1/2002] A page and a half of the contents will be released on April 10, 2004; this reportedly is the full content of the briefing. [Washington Post, 4/10/2004] The briefing, as released, states as follows (note that the spelling of certain words are corrected and links have been added):
bullet Clandestine, foreign government, and media reports indicate bin Laden since 1997 has wanted to conduct terrorist attacks in the US (see December 1, 1998). Bin Laden implied in US television interviews in 1997 and 1998 that his followers would follow the example of World Trade Center bomber Ramzi Yousef and “bring the fighting to America” (see May 26, 1998).
bullet After US missile strikes on his base in Afghanistan in 1998, bin Laden told followers he wanted to retaliate in Washington, according to a -REDACTED-service (see December 21, 1998).
bullet An Egyptian Islamic Jihad (EIJ) operative told -REDACTED- service at the same time that bin Laden was planning to exploit the operative’s access to the US to mount a terrorist strike.
bullet The millennium plotting in Canada in 1999 may have been part of bin Laden’s first serious attempt to implement a terrorist strike in the US. Convicted plotter Ahmed Ressam has told the FBI that he conceived the idea to attack Los Angeles International Airport himself (see December 14, 1999), but that bin Laden lieutenant Abu Zubaida encouraged him and helped facilitate the operation. Ressam also said that in 1998 Abu Zubaida was planning his own US attack (see Late March-Early April 2001 and May 30, 2001).
bullet Ressam says bin Laden was aware of the Los Angeles operation.
bullet Although bin Laden has not succeeded, his attacks against the US Embassies in Kenya and Tanzania in 1998 (see 10:35-10:39 a.m., August 7, 1998) demonstrate that he prepares operations years in advance and is not deterred by setbacks. Bin Laden associates surveyed our embassies in Nairobi and Dar es Salaam as early as 1993 (see Late 1993-Late 1994), and some members of the Nairobi cell planning the bombings were arrested and deported in 1997.
bullet Al-Qaeda members—including some who are US citizens—have resided in or traveled to the US for years, and the group apparently maintains a support structure that could aid attacks (see January 25, 2001). Two al-Qaeda members found guilty in the conspiracy to bomb our embassies in East Africa were US citizens (see September 15, 1998), and a senior EIJ member lived in California in the mid-1990s (see November 1989 and September 10, 1998).
bullet A clandestine source said in 1998 that a bin Laden cell in New York was recruiting Muslim-American youth for attacks (see October-November 1998).
bullet “We have not been able to corroborate some of the more sensational threat reporting, such as that from a [REDACTED] service in 1998 saying that bin Laden wanted to hijack a US aircraft to gain the release of ‘Blind Sheikh’ Omar Abdul-Rahman and other US-held extremists” (see 1998, December 4, 1998, and May 23, 2001). [9/11 Commission, 7/24/2004, pp. 223] According to the Washington Post, this information came from a British service. [Washington Post, 5/18/2002]
bullet Nevertheless, FBI information since that time indicates patterns of suspicious activity in this country consistent with preparations for hijackings or other types of attacks, including recent surveillance of federal buildings in New York (see May 30, 2001).
bullet The FBI is conducting approximately 70 full-field investigations throughout the US that it considers bin Laden-related (see August 6, 2001). CIA and the FBI are investigating a call to our embassy in the UAE in May saying that a group or bin Laden supporters was in the US planning attacks with explosives (see May 16-17, 2001). [9/11 Commission, 7/24/2004, pp. 223]
In retrospect, the briefing is remarkable for the many warnings that apparently are not included (see for instance, from the summer of 2001 prior to August alone: May 2001, June 2001, June 12, 2001, June 19, 2001, Late Summer 2001, July 2001, July 16, 2001, Late July 2001, Late July 2001, Summer 2001, June 30-July 1, 2001, July 10, 2001, and Early August 2001). According to one account, after the PDB has been given to him, Bush tells the CIA briefer, “You’ve covered your ass now” (see August 6, 2001). Incredibly, the New York Times later reports that after being given the briefing, Bush “[breaks] off from work early and [spends] most of the day fishing.” [New York Times, 5/25/2002] In 2002 and again in 2004, National Security Adviser Rice will incorrectly claim under oath that the briefing only contained historical information from 1998 and before (see May 16, 2002 and April 8, 2004).

According to journalist and author Ron Suskind, just after a CIA briefer presents President Bush with the later infamous PDB (Presidential Daily Briefing) item entitled “Bin Laden Determined to Strike in US” (see August 6, 2001), Bush tells the briefer, “You’ve covered your ass, now.” This account is from Suskind’s 2006 book The One Percent Doctrine, which is based largely on anonymous accounts from political insiders. In the book, after describing the presentation of the PDB, Suskind will write: “And, at an eyeball-to-eyeball intelligence briefing during this urgent summer, George W. Bush seems to have made the wrong choice. He looked hard at the panicked CIA briefer. ‘All right,’ he said. ‘You’ve covered your ass, now.’” [Suskind, 2006, pp. 2; Washington Post, 6/20/2006]

The CIA’s Presidential Daily Briefing (PDB) given to President Bush on this day (see August 6, 2001) contains the important line, “The FBI is conducting approximately 70 full field investigations throughout the US that it considers bin Laden-related.” Bush will state in 2004 that, based on this, “I was satisfied that some of the matters were being looked into.” National Security Adviser Rice will explain that since the FBI had 70 “full-field investigations under way of cells” in the US, “there was no recommendation [coming from the White House] that we do something about” the large number of warnings coming in. However, the number and content of the FBI investigations appears grossly exaggerated. The FBI later will reveal that the investigations are not limited to al-Qaeda and do not focus on al-Qaeda cells. Many were criminal investigations, which typically are not likely to help prevent future terrorist acts. An FBI spokesman will say the FBI does not know how that number got into Bush’s PDB. The 9/11 Commission will later conclude, “The 70 full-field investigations number was a generous calculation that included fund-raising investigations. It also counted each individual connected to an investigation as a separate full-field investigation. Many of these investigations should not have been included, such as the one that related to a dead person, four that concerned people who had been in long-term custody, and eight that had been closed well before August 6, 2001.” [Newsday, 4/10/2004; Associated Press, 4/11/2004; 9/11 Commission, 7/24/2004, pp. 262, 535]

The Bush administration holds no high-level meetings prior to 9/11 to discuss the ‘Bin Laden Determined to Strike in US’ Presidential Daily Briefing (PDB) given to President Bush on August 6, 2001 (see August 6, 2001). Counterterrorism “tsar” Richard Clarke will later suggest that 9/11 might have been stopped “if [National Security Adviser] Rice and the president had acted personally, gotten involved, shaken the trees, gotten the Cabinet members involved when they had ample warning in June and July and August that something was about to happen.… [Rice] said that the president received 40 warnings face to face from the director of central intelligence that a major al-Qaeda attack was going to take place and she admitted that the president did not have a meeting on the subject, did not convene the Cabinet. She admitted that she didn’t convene the Cabinet. And as some of the [9/11 Commissioners] pointed out, this was in marked contrast to the way the government operated in December of 1999, when it had similar information and it successfully thwarted attacks.” [ABC News, 4/8/2004] Former CIA official Larry Johnson will similarly comment, “At a minimum, the details in the 6 August PDB should have motivated Rice to convene a principals’ meeting. Such a meeting would have ensured that all members of the president’s national security team were aware of the information that had been shared with the president. George Bush should have directed the different department heads to report back within one week on any information relevant to the al-Qaeda threat. Had he done this there is a high probability that the FBI field agents concerns about Arabs taking flight training would have rung some bells. There is also a high probability that the operations folks at CIA would have shared the information they had in hand about the presence of al-Qaeda operators in the United States.” [Tom Paine (.com), 4/12/2004] There will be one cabinet-level principals meeting to discuss terrorism on September 4, 2001, but no evidence has been released suggesting the PDB or the possibility of al-Qaeda attacking the US was discussed (see September 4, 2001).

One day after President Bush receives a Presidential Daily Briefing entitled, “Bin Laden Determined to Strike in US,” a version of the same material is given to other top government officials. However, this Senior Executive Intelligence Brief (SEIB) does not contain the most important information from Bush’s briefing. It does not mention that there are 70 FBI investigations into possible al-Qaeda activity, does not mention a May 2001 threat of US-based explosives attacks, and does not mention FBI concerns about recent surveillance of buildings in New York City. The Associated Press will report that this type of memo “goes to scores of Cabinet-agency officials from the assistant secretary level up and does not include raw intelligence or sensitive information about ongoing law enforcement matters” due to fear of media leaks. SEIBs were sent to many more officials during the Clinton administration. The Associated Press will also state that “some who saw the memo said they feared it gave policy-makers and members of the congressional intelligence committees a picture of the domestic threat so stale and incomplete that it didn’t provide the necessary sense of urgency one month before the Sept. 11 attacks.” [Associated Press, 4/13/2004] Attorney General John Ashcroft will later say he does not recall seeing the SEIB before 9/11 (see Between August 7 and September 10, 2001).

On August 7, 2001, a version of the Presidential Daily Briefing (PDB) entitled “Bin Laden Determined to Strike in US” given to President Bush the day before is sent to other top US officials (see August 7, 2001). This version, called an SEIB, has the same title as the PDB but contains less classified information. Attorney General John Ashcroft - the head of law enforcement in the US - will later claim that he does not remember seeing this SEIB before 9/11. He will say he was at a conference in Chicago at the time and he does not remember his staff briefing him about it later. In the Clinton administration, the attorney general was a regular recipient of the same PDB given to the president. [9/11 Commission, 4/13/2004]

CIA records show that CIA Director George Tenet briefed President Bush twice in August—once in Crawford, Texas, on August 17, and once in Washington, on August 31. [Washington Post, 4/15/2004] In Tenet’s 2007 book, he will briefly mention that “A few weeks after the August 6 PDB [titled ‘Bin Laden Determined to Strike in US’ (see August 6, 2001)] was delivered, I followed it to Crawford to make sure the president stayed current on events. That was my first visit to the ranch.” [Tenet, 2007, pp. 145] Later asked about what he told Bush at this meeting, Tenet will only say, “I held nothing back from the president. He understood our concerns about threats. He understood what we were doing around the world at the time.” [MSNBC, 5/7/2007] By the time of the second briefing, Tenet has been briefed about Zacarias Moussaoui’s arrest (see August 23, 2001), but, apparently, he fails to tell Bush about it. [Washington Post, 4/15/2004] In April 2004, Tenet will testify under oath before the 9/11 Commission that he had no direct communication with President Bush during the month of August. [New York Times, 4/15/2004] This is quickly discovered to be untrue. A CIA spokesperson will then claim, “He momentarily forgot [about the briefings]” (see April 14, 2004). [Washington Post, 4/15/2004] Tenet will personally brief Bush six more times before 9/11 and will still apparently fail to mention Moussaoui to him (see September 1-8, 2001).

With President Bush back in Washington after a long vacation, CIA Director George Tenet resumes personally delivering the Presidential Daily Briefing (PDB) to him. Tenet has one meeting with Bush on August 31, 2001, after Bush’s return (see August 17 and 31, 2001), and then briefs him six more times in the first eight days of September. Bush is out of town the next few days, so he is briefed by other CIA personnel. [Agence France-Presse, 4/15/2004] By this time, Tenet has been told about the arrest of suspected terrorist Zacarias Moussaoui (see August 23, 2001). But there is no evidence he mentions this to Bush before 9/11. Further, on August 23, 2001, the CIA watchlisted 9/11 hijackers Khalid Almihdhar and Nawaf Alhazmi and began looking for them in the US (see August 23, 2001), but there’s no evidence Tenet or anyone else briefed Bush about this, either.

President Bush talks about the Presidential Daily Briefing (PDB) he was given on August 6, 2001, entitled “Bin Laden Determined to Strike in US.” He claims, “There was nothing in this report to me that said, ‘Oh, by the way, we’ve got intelligence that says something is about to happen in America.‘… There was nothing in there that said, you know, ‘There is an imminent attack.’ That wasn’t what the report said. The report was kind of a history of Osama’s intentions.” [Associated Press, 4/12/2004] He adds, “[T]he PDB was no indication of a terrorist threat. There was not a time and place of an attack. It said Osama bin Laden had designs on America. Well, I knew that. What I wanted to know was, is there anything specifically going to take place in America that we needed to react to.… I was satisfied that some of the matters were being looked into. But that PDB said nothing about an attack on America. It talked about intentions, about somebody who hated America—well, we knew that.… Had I known there was going to be an attack on America, I would have moved mountains to stop the attack.” [US President, 4/19/2004] The complete text of the PDB was released the day before Bush’s comments and in fact the PDB does very clearly discuss an imminent attack on the US. For instance, it says that FBI information “indicates patterns of suspicious activity in this country consistent with preparations for hijackings or other types of attacks, including recent surveillance of federal buildings in New York.” And it discusses a call to a US “embassy in the UAE in May [2001] saying that a group of bin Laden supporters was in the US planning attacks with explosives” (see August 6, 2001).
