On December 6, 2007, the CIA admitted that it had destroyed videotapes recordings of CIA interrogations of terrorism suspects involving harsh interrogation techniques, tapes which critics suggest may have documented the use of torture by the CIA, such as waterboarding. The tapes were made in 2002 as part of a secret detention and interrogation program, and were destroyed in November 2005. The reason cited for the destruction of the tapes was that the tapes posed a security risk for the interrogators shown on the tapes. Yet the department also stated that the tapes "had no more intelligence value and were not relevant to any inquiries". In response, Senate Armed Services Committee Chairman Carl Levin (D-Michigan) stated: "You'd have to burn every document at the CIA that has the identity of an agent on it under that theory." Other Democrats in Congress also made public statements of outrage about the destruction of the tapes, suggesting that a violation of law had occurred.
