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.
