Several congressional committees want the FBI director to explain why one of his agents ordered the release of Anwar al-Awlaki from federal custody on Oct. 10, 2002, when there was an outstanding warrant for the American Muslim cleric's arrest. The cleric was held by customs agents at JFK International Airport in New York City in early morning of Oct. 10, 2002, until FBI Agent Wade Ammerman ordered his release - even though a warrant for the cleric's arrest on passport fraud was still active. The warrant was generated by the Joint Terrorism Task Force in San Diego, which considered the cleric a tier one" target because of his connections to at least three of the 9/11 hijackers. The passport fraud warrant was described ... as a holding charge that would allow federal investigators to pressure al-Awlaki over his 9/11 contacts. The warrant was pulled by a judge in Colorado, after the cleric entered the U.S.. After al-Awlaki re-entered the U.S. in the fall of 2002 with the FBI's help, the cleric then appeared in a high-profile investigation, in which Agent Ammerman was a lead investigator. Former FBI agents say Ammerman would have needed permission from higher up in the bureau to let al-Awlaki go. Former FBI agents, familiar with al-Awlaki's re-entry in October 2002, say only two scenarios seem to explain what happened. The FBI was tracking the cleric for intelligence or the FBI was working with the cleric and saw him as a "friendly contact."
