[The top counterterrorism adviser to President Clinton and Mr. Bush, Richard Clarke will] be featured in a documentary advancing [a] theory that the Central Intelligence Agency tried to turn two of the 9/11 hijackers into double agents while they resided in the United States in the years leading up to the attacks. During the 9/11 Commission's investigation of the attacks, the CIA said it didn't know the location of the hijackers Clarke refers to, Nawaf al-Hazmi and Khalid al-Mihdhar. In the documentary, Clarke ... concludes that the CIA director at the time, George Tenet, ordered the cover-up after the recruitment effort failed. In response to that accusation, Tenet released a written statement saying that Clarke has suddenly invented baseless allegations which are belied by the record and unworthy of serious consideration."
