The FBI identified Anwar Awlaki as a likely conspirator in the 2001 Sep11 attacks as early as September 27 of that year, as he had bought the airline tickets to bring three of the hijackers into the United States. After that finding, Awlaki was invited by the Congressional Muslim Staffers Association to lead their prayers, praised by New York Times reporter Laurie Goodstein as "a new generation of Muslim leader capable of merging East and West", and invited by the Defense Department to a luncheon with the Secretary of the Office of General Counsel. He was also briefly arrested in 2002, but released on the order of David Gaouette of the U.S. Attorney's Office in Denver.
