A former FBI agent who was embedded in the CIA’s Bin Laden unit, Mark Rossini, claims the CIA was fully aware that the 9/11 hijackers were in the United States planning an attack. Rather than inform the FBI, the CIA tried to recruit two of the hijackers for a “false-flag” operation, which quickly spiraled out of control. The failed mission raises urgent questions about government secrecy, intelligence failures, and what really happened before 9/11.
