Barbara Grewe, a key investigator on the Justice Department inspector general’s investigation of the FBI’s failures before 9/11, moves to the 9/11 Commission. [University of Michigan Law School, 3/7/2005] She was recommended to the Commission by a former colleague who worked at the office of inspector general at the Justice Department. [University Record Online, 3/14/2005] As special investigative counsel at the Justice Department’s office of the inspector general between July and December 2002 she had investigated and reported on the FBI’s handling of intelligence prior to 9/11, and directed part of the investigation into information sharing between the FBI and CIA, missed opportunities to locate the hijackers before 9/11, and earlier warnings about terrorists using airplanes as weapons. This is similar to the work she does on the 9/11 Commission. According to a press release for a lecture she will give in 2005, Grewe also “drafted and edited” the “relevant sections” of the Justice Department’s final report. [University of Michigan Law School, 3/7/2005; Center for American Progress Action Fund, 4/16/2008] However, it is unclear how she could have done this, as she left the Justice Department’s investigation in 2003. Although December 2002 is early on in the Justice Department inspector general’s probe, the following important interviews have been conducted by this time: 
Tom Wilshire, a CIA officer later detailed to the FBI who was involved in many pre-9/11 intelligence failures (see 9:30 a.m. – 4:00 p.m. January 5, 2000, March 5, 2000, May 15, 2001, Mid-May 2001, Late May, 2001, July 23, 2001, August 22, 2001, and August 24, 2001); [9/11 Commission, 7/24/2004, pp. 502] “Michael,” a female CIA officer who had blocked notification to the FBI saying that one of the hijackers, Khalid Almihdhar, had a US visa (see Around 7:00 p.m. January 5, 2000 and January 6, 2000); [9/11 Commission, 7/24/2004, pp. 502] Dina Corsi, an FBI official who withheld intelligence information from criminal investigators in the summer of 2001 (see June 12-September 11, 2001, Before August 22, 2001, August 27-28, 2001, August 28, 2001, and August 28-29, 2001); [9/11 Commission, 7/24/2004, pp. 474] Clark Shannon, a CIA officer who withheld information about Almihdhar from the FBI (see June 11, 2001); [9/11 Commission, 7/24/2004, pp. 537] Margaret Gillespie, an FBI agent detailed to the FBI involved in information sharing problems (see (Late May-Early June) and August 21-22, 2001); [9/11 Commission, 7/24/2004, pp. 538] Robert Fuller, an FBI agent who searched for Almihdhar in the US just before the 9/11 attacks, but failed to find him (see September 4, 2001, September 4-5, 2001, and September 4-5, 2001); [9/11 Commission, 7/24/2004, pp. 539] Russell Fincher and Steve Bongardt, FBI agents from whom the CIA withheld information (see June 11, 2001, June 12-September 11, 2001, and August 29, 2001); [9/11 Commission, 7/24/2004, pp. 537] Sherry Sabol, an attorney involved in errors in the Moussaoui and Almihdhar cases (see August 22-28, 2001 and August 28-29, 2001); [9/11 Commission, 7/24/2004, pp. 538] An FBI official who handled an al-Qaeda informer in Pakistan (see January 4, 2001); [9/11 Commission, 7/24/2004, pp. 537] Harry Samit (see August 15-20, 2001), Greg Jones (see August 27, 2001), John Weess (see August 16, 2001), and Coleen Rowley (see May 21, 2002), FBI officials who worked on the Moussaoui case; [9/11 Commission, 7/24/2004, pp. 531, 540] Rodney Middleton, acting head of the FBI’s bin Laden unit before 9/11 (see July 27, 2001 and after); and [9/11 Commission, 7/24/2004, pp. 538] Jennifer Maitner, an FBI official involved in the Phoenix memo and President Bush’s August 6 presidential daily briefing (see July 10, 2001, July 27, 2001 and after, and (August 4-5, 2001)). [9/11 Commission, 7/24/2004, pp. 536]
Late 2003: Key Investigator Transferred within 9/11 Commission
Barbara Grewe, the leader of the 9/11 Commission’s team that is investigating law enforcement and intelligence collection inside the US, is moved to another part of the investigation. 9/11 Commission Executive Director Philip Zelikow will say that Grewe is brought “into the CIA part of the work and give[n]… a lead role in developing our draft on some of the specific FBI-CIA operational problems before 9/11 and on the ‘summer of threat.’” Grewe had previously worked on similar aspects of the Justice Department inspector general’s report into the FBI’s pre-9/11 failings (see Between December 2002 and May 2003). Zelikow will add, “She ultimately became our lead drafter for chapter eight of the report.” [Zelikow and Shenon, 2007 
] That chapter, entitled “The System Was Blinking Red,” will deal with warnings of a terrorist attack on the US in the summer of 2001, the government’s response to them, and failures to share intelligence at that time. [9/11 Commission, 7/24/2004, pp. 254-277]
Before August 2007: Key 9/11 Investigator Hired by CIA Contractor
Former 9/11 Commission staffer Barbara Grewe is hired by the MITRE Corporation. Grewe was a key investigator on the Commission and on the Justice Department inspector general’s investigation of 9/11, where she had focused on FBI and CIA failures (see Between December 2002 and May 2003 and Late 2003). [Bellvue University, 8/9/2007; Center for American Progress Action Fund, 4/16/2008] The MITRE Corporation is closely linked to the CIA and other government agencies. For example, in December 2000 CIA Director George Tenet awarded the Intelligence Community Seal Medallion to Allan McClure of the MITRE Corporation for his help developing software and hardware to facilitate the exchange of information. [MITRE, 12/6/2000] After leaving the Commission, Grewe had worked as an associate general counsel at the Government Accountability Office (GAO). [Florida Atlantic University, 1/2005; National Security Law Report, 8/2005 ; Center for American Progress Action Fund, 4/16/2008] There she supervised the GAO’s work related to the 9/11 Commission’s recommendations. [University of Michigan Law School, 3/7/2005; University Record Online, 3/14/2005] It is unclear exactly when she moves from the GAO to MITRE, but it must happen some time before August 2007. [Bellvue University, 8/9/2007] At MITRE, Grewe is a senior policy administrator and advises on information sharing issues regarding the intelligence community, the federal government, and local partners. [Bellvue University, 8/9/2007; Center for American Progress Action Fund, 4/16/2008] According to a MITRE press release, she also works as a “principal multi-discipline systems engineer.” [MITRE, 4/2008]
