Ali Soufan resigns from the FBI. As an Arabic-speaking Muslim who joined the FBI long before 9/11 (see November 1997), Soufan has become one of the FBI’s best interrogators and experts on al-Qaeda. However, in a 2011 book, he will claim that he grew increasingly frustrated due to the CIA’s opposition to his work. “It was… clear that some high-level people at the time were specifically targeting me—I was told that by more than a few FBI executives and CIA colleagues,” he will write. “Ever since I had been interviewed by the 9/11 Commission, I was a marked man.” In 2004, Soufan gave information to the 9/11 Commission that made the CIA look bad. He will claim there were instances when the FBI wanted him to go overseas as part of an investigation but the CIA tried to prevent him from doing so. [Soufan, 2011, pp. 515-517, 522-523]
