After her vetting, Aulaqi (Awlaki) was invited to and attended a luncheon at the Pentagon in the secretary of the Army's Office of Government Counsel." Awlaki, a Yemeni-American cleric who was questioned by the FBI several times immediately following 9/11 because of his alleged ties to three hijackers that were onboard the plane that crashed into the Pentagon, is also suspected of having ties to Ft. Hood shooter Major Nidal Malik Hasan and to the Christmas Day bomber, Umar Farouk Abdulmutallab. The Pentagon has not given an explanation for how Awlaki ended up as a guest at the Defense Department headquarters. According to Fox News, a top-ranking FBI official said that at the time Awlaki came to the Pentagon, there was a great deal of "arrogance" regarding the background checking process there.The official said, as quoted by Fox, "They vetted people politically and showed indifference toward security and intelligence advice of others."Awlaki is allegedly believed to be hiding in Yemen.
