October 11, 2001: Early Account of Able Danger Remains Classified

Dr. Eileen Preisser testifies before a congressional briefing. Dr. Preisser was one of four analysts in the US Army’s Land Information Warfare Activity (LIWA) supporting Able Danger in late 1999 and 2000 (see Fall 1999). While her testimony remains classified, the next day, Representative Christopher Shays (R-CT) gives a brief summary: “In a briefing we had yesterday, we had Eileen [Preisser], who argues that we don’t have the data we need because we don’t take all the public data that is available and mix it with the security data. And just taking public data, using, you know, computer systems that are high-speed and able to digest, you know, literally floors’ worth of material, she can take relationships that are seven times removed, seven units removed, and when she does that, she ends up with relationships to the bin Laden group where she sees the purchase of chemicals, the sending of students to universities. You wouldn’t see it if you isolated it there, but if that unit is connected to that unit, which is connected to that unit, which is connected to that unit, you then see the relationship. So we don’t know ultimately the authenticity of how she does it, but when she does it, she comes up with the kind of answer that you have just asked, which is a little unsettling.” [US Congress. House. Committee on Government Reform. Subcommittee on National Security, Veterans Affairs and International Relations, 10/12/2001] Note that according to some media accounts, the CIA monitored Mohamed Atta purchasing large quantities of chemicals in Germany in the spring of 2000 (see January-May 2000). Atta also sends a series of e-mails to the US in the spring of 2000, inquiring about flight school opportunities for himself and a “small group” of his associates (see January-March 2000). Dr. Preisser is apparently willing to testify about her role in how Able Danger uncovered Atta’s name, but in September 2005 she is prohibited from publicly testifying before Congress (see September 21, 2005).
