FBI headquarters agent Dina Corsi asks the FBI’s New York field office to open an intelligence investigation into future 9/11 hijacker Khalid Almihdhar and locate him in the US. Corsi’s written request mentions Almihdhar’s arrival in the US in July 2001 (see July 4, 2001), his previous travel to the US in January 2000 with Nawaf Alhazmi (see January 15, 2000), his attendance at al-Qaeda’s Malaysia summit (see January 5-8, 2000), his association with an al-Qaeda communications hub in Yemen (see Early 2000-Summer 2001), and similarities between his travel and that of Fahad al-Quso, Ibrahim al-Thawar (a.k.a. Nibras), and Khallad bin Attash (see January 13, 2000), operatives involved in the bombing of the USS Cole. Corsi does not mention that the CIA knows bin Attash also attended the Malaysia summit, as this information has not officially been passed to the FBI yet. [US Department of Justice, 11/2004, pp. 304 ]
