Omar al-Bayoumi.Omar al-Bayoumi. [Source: Fox News]Omar al-Bayoumi, a suspected Saudi spy, goes to great lengths to help future 9/11 hijackers Nawaf Alhazmi and Khalid Almihdhar settle in San Diego. Supposedly, al-Bayoumi meets them by chance in a Los Angeles restaurant and encourages them to move to San Diego, but the accounts of the meeting are highly doubtful (see February 1, 2000). The FBI’s “best source” in San Diego will later say that al-Bayoumi “must be an intelligence officer for Saudi Arabia or another foreign power.” A former top FBI official working on the al-Bayoumi investigation claims, “We firmly believed that he had knowledge [of the 9/11 plot], and that his meeting with them that day was more than coincidence.” [Newsweek, 7/28/2003]
bullet When Alhazmi and Almihdhar move into apartment 150 in the Parkwood Apartments in San Diego in early February, they indicate on their rental application that they have been staying at al-Bayoumi’s apartment in the same apartment complex since January 15, the day they arrived in the US (see January 15-February 2, 2000). (This would suggest the alleged accidental restaurant meeting never took place.) [Federal Bureau of Investigation, 10/3/2001 pdf file]
bullet He is the co-signer and guarantor for their rental application, because they do not have established credit. [Federal Bureau of Investigation, 10/3/2001 pdf file]
bullet He pays $1,500 cash for their first month’s rent and security deposit. Some FBI officials claim the hijackers immediately pay him back, others claim they do not. [Newsweek, 11/24/2002; US Congress, 7/24/2003 pdf file]
bullet The apartment manager will later claim al-Bayoumi occasionally paid rent for Alhazmi and Almihdhar on other occasions. [Federal Bureau of Investigation, 10/3/2001 pdf file]
bullet Shortly after they arrive in San Diego, al-Bayoumi throws a welcoming party to introduce them to the local Muslim community. [Washington Post, 12/29/2001] One attendee will later say an al-Bayoumi party “was a big deal… it meant that everyone accepted them without question.” [San Diego Union-Tribune, 10/25/2001]
bullet He also introduces hijacker Hani Hanjour to the community a short time later, and Hanjour is seen in his apartment later in the year (see Early 2000). [San Diego Union-Tribune, 9/14/2002]
bullet Cayson Bin Don, a friend of al-Bayoumi, will later say al-Bayoumi “spent a lot of time at Alhazmi and Almihdhar’s apartment.” [Federal Bureau of Investigation, 10/8/2001 pdf file]
bullet Al-Bayoumi apparently loans the hijackers his cell phone until they can get phone service in their own apartment. On February 15, 2000, someone trying to call al-Bayoumi on his phone has the call answered by Alhazmi instead. [9/11 Commission, 7/24/2004, pp. 516]
bullet He tasks an acquaintance, Mohdar Abdullah, to serve as their translator and help them get driver’s licenses, Social Security cards, information on flight schools, and more. [San Diego Union-Tribune, 9/14/2002; US Congress, 7/24/2003 pdf file]

Cayson Bin Don, a.k.a. Clayton Morgan.Cayson Bin Don, a.k.a. Clayton Morgan. [Source: Fox News]On February 1, 2000, 9/11 hijackers Nawaf Alhazmi and Khalid Almihdhar allegedly meet Omar al-Bayoumi, a suspected Saudi spy, by pure chance. Alhazmi and Almihdhar had arrived in Los Angeles from overseas on January 15 (see January 15, 2000). On February 1, al-Bayoumi drives about two hours from where he lives in San Diego to Los Angeles. He is driving with Cayson Bin Don, an US citizen formerly known as Clayton Morgan who converted to Islam and became a supporter of radical militant causes. [FrontPage Magazine, 4/27/2005]
Al-Bayoumi Met with Saudi Consulate Official - Al-Bayoumi just had a one hour meeting with Fahad al Thumairy, an employee of the Saudi embassy suspected to have radical militant ties. (Al Thumairy will later be deported from the US due to alleged terrorist links (see May 6-8, 2003).) What al-Bayoumi and al Thumairy discuss is unknown, but phone records indicate they had been in contact since 1998 (see December 1998-December 2000). [Graham and Nussbaum, 2004, pp. 12-13]
Meeting at Restaurant - After the meeting, al-Bayoumi rejoins Cayson Bin Don and they go to a Middle Eastern restaurant several miles from the Los Angeles airport. Al-Bayoumi and Bin Don will both be interviewed about this later and describe similar stories. Supposedly, al-Bayoumi hears Arabic being spoken at an adjacent table, and invites the two strangers, Alhazmi and Almihdhar, to join them. Alhazmi says that he and Almihdhar do not feel comfortable in Los Angeles as they find the city too big and intimidating. Al-Bayoumi offers to be of help if the two of them decide to move to San Diego. Al-Bayoumi and Bin Don then leave the restaurant and visit the Culver City mosque a few blocks away (Al Thumairy is also the imam at that mosque). Then they return to San Diego. The two hijackers move to San Diego a few days later, and al-Bayoumi helps them extensively. [Federal Bureau of Investigation, 10/8/2001 pdf file; Graham and Nussbaum, 2004, pp. 12-13; 9/11 Commission, 7/24/2004, pp. 217-218] Al-Bayoumi will later claim that this first contact with the hijackers is accidental. However, one FBI source will later recall that before al-Bayoumi drove to Los Angeles that day, he said he was going “to pick up visitors.” [US Congress, 7/24/2003 pdf file; Newsweek, 7/28/2003]
Problems with Account - There are numerous problems with Bin Don’s account. He recalls the meeting took place between December 1999 and February 2000, so it just as easily could have taken place on January 15, the day the hijackers first arrived. Also, when initially questioned by the FBI, he will claim that he first met the two hijackers at a party in San Diego. Asked why he failed to remember the restaurant meeting, he will point out he has ADD (attention deficit disorder). He will also concede that there was a “remote possibility” he could have been used as an alibi or cover by al-Bayoumi for the meeting. [Federal Bureau of Investigation, 10/8/2001 pdf file] Additionally, several days after 9/11, Bin Don will tell two police officers that he supported the 9/11 attack and that he would never tip authorities off if he knew of an impending attack. Later in the month, he attempts to purchase an assault rifle and handgun. Then, in comments to the New York Post in October 2001, he says, “I would consider it more noble for me to go and get myself out of the country, renounce my citizenship, end up in Afghanistan, pick up a gun and fight alongside everyone else against the enemy—American soldiers.” [FrontPage Magazine, 4/27/2005] The 9/11 Commission will later note that there are inconsistencies and problems with both al-Bayoumi’s and Bin Don’s accounts of the meeting. The Commission will conclude: “We do not know whether the lunch encounter occurred by chance or design. We know about it because al-Bayoumi told law enforcement that it happened.” [9/11 Commission, 7/24/2004, pp. 217] A former top FBI official working on the al-Bayoumi investigation will later claim, “We firmly believed that [al-Bayoumi] had knowledge [of the 9/11 plot], and that his meeting with them that day was more than coincidence.” [Newsweek, 7/28/2003] Senator Bob Graham (D-FL), co-chair of the 9/11 Congressional Inquiry, will comment, “That a suspected Saudi spy would drive 125 miles to a meeting at the Saudi consulate in Los Angeles, where he would meet with a consular officer with suspected terrorist ties, and then drive another 7 miles to the one Middle Eastern restaurant—out of more than 134 Middle Eastern restaurants in Los Angeles—where he would happen to sit next to two future terrorists, to whom he would happen to offer friendship and support, cannot credibly be described as a coincidence.” [Graham and Nussbaum, 2004, pp. 12-13]
Hijackers Already Living with Al-Bayoumi - Furthermore, there is evidence the two hijackers actually stayed in al-Bayoumi’s San Diego apartment from January 15, the day they arrived, until the day after this supposed meeting (see January 15-February 2, 2000).
