FBI officials maintain that 9/11 hijackers Nawaf Alhazmi and Khalid Almihdhar did not have anyone knowingly supporting their al-Qaeda activities when they lived in San Diego in 2000 and 2001.
FBI: Hijackers Had No Witting Support in San Diego – Larry Mefford, who was the FBI’s head of counterterrorism until November 2003, says: “Maybe there’s been something new. But as of the time of my retirement, there was no credible indication that anyone in Southern California helped the two terrorists with knowledge of the 9/11 plot.” And Richard Garcia, head of the FBI in Los Angeles, says, “If there was support, I think it was unwitting.” Garcia says that whatever support the hijackers received was from Muslims innocently helping other Muslims.
9/11 Commission Suggests Otherwise – However, the 9/11 Commission’s final report, published the same day as these comments, suggests otherwise. The report details extensive help the hijackers received, and strongly implies that at least some of their helpers, such as Mohdar Abdullah and Anwar al-Awlaki, were radical Islamists with a similar agenda as the hijackers. For instance, the report comments, “We believe it is unlikely that [Alhazmi] and Almihdhar… would have come to the United States without arranging to receive assistance from one or more individuals informed in advance of their arrival.” [Los Angeles Times, 7/24/2004]
9/11 Congressional Inquiry Also Suggests Otherwise – The 9/11 Congressional Inquiry’s final report concluded that at least six 9/11 hijackers received “substantial assistance” from associates in the US, though it is “not known to what extent any of these contacts in the United States were aware of the plot.” The inquiry focused on associates in San Diego, including Abdullah and al-Awlaki (see July 24, 2003).

What about Abdullah and Al-Awlaki? – In late 2003, new evidence emerged that Abdullah might have had foreknowledge of the 9/11 attacks, but he was deported anyway, in May 2004 (see May 21, 2004). In late 2004, several months after the comments by Mefford and Garcia, more evidence against him will emerge, causing the FBI to reopen its investigation into him (see September 2003-May 21, 2004). In 2008, US intelligence will finally conclude that al-Awlaki is an al-Qaeda operative (see February 27, 2008), and he will be connected to a number of attacks in the US.
