Shortly after 9/11, the FBI begins to suspect that Anwar al-Awlaki, an imam to several of the 9/11 hijackers, may have had some connection to the 9/11 plot. They interview him repeatedly, but cannot find enough evidence to charge him, and he cannot be deported since he is a US citizen. Investigators discover he had been arrested more than once for soliciting prostitutes. They learn he is consorting with prostitutes in Virginia, and contemplate jailing him on an obscure law against transporting prostitutes across state lines. However, this plan collapses when he leaves the US unexpectedly in March 2002. [US News and World Report, 6/13/2004] But on October 10, 2002, he makes a surprise return to the US. His name is on a terrorist watch list and he is detained when his plane lands in New York City. Customs agents notify the FBI, but they are told that his name was taken off the watch list just the day before. He is released after only three hours. It has not been explained why he name was taken off the list. Throughout 2002, al-Awlaki is also the subject of an active Customs investigation into money laundering called Operation Greenquest, but he is not arrested for this either, or for the earlier contemplated prostitution charges. [WorldNetDaily, 8/16/2003] At the time, the FBI is fighting Greenquest, and Customs officials will later accuse the FBI of sabotaging Greenquest investigations (see After March 20, 2002-Early 2003). While in the US, al-Awlaki visits the Fairfax, Virginia, home of Ali al Timimi, the leader of a nearby Islamic center. According to a later court filing, al-Awlaki attempts to get al Timimi to discuss the recruitment of young Muslims for militant causes, but al Timimi does not show interest. Al Timimi will later be sentenced to life in prison in the US for inciting young Muslims to fight in Afghanistan shortly after 9/11. [Washington Post, 2/27/2008] Al-Awlaki then leaves the US again. The FBI will later admit they were “very interested” in al-Awlaki and yet failed to stop him from leaving the country. One FBI source says, “We don’t know how he got out.” [US News and World Report, 6/13/2004] He will allegedly take part in other militant attacks (see September 15, 2006). By 2008, US intelligence will conclude that he is linked to al-Qaeda (see February 27, 2008).
