The FBI's Office Of The Inspector General Report On The Continuing Review Of The Malaysia Meeting

I read from the FBI's Office of the Inspector General (OIG) report which was publicly released in June 2006. In this section of the chapter, the fifth and final opportunity for the FBI to locate Khalid al-Mihdhar and Nawaf al-Hazmi occur in late August 2001, when it was informed that Mihdhar and Hazmi had traveled to the United States. The FBI learned in August 2001 that Mihdhar had entered the United States in July 2001 and that Mihdhar and Hazmi had previously traveled together to the United States in January 2000. On August 29, the FBI began an investigation to locate Mihdhar, but it did not assign great urgency or priority to the investigation. The New York FBI criminal agents who wanted to participate in the investigation were specifically prohibited from doing so because of concerns about the wall and the procedures to keep criminal and intelligence investigations separate. The FBI did not locate Mihdhar before the September 11 attacks.
