In 2006, then-President George W. Bush adamantly denied that the U.S. used torture against suspected terrorists. Tuesday's release of the Senate report on the CIA's post-9/11 interrogation practices reveals that statement to be false.

The 500-page summary of the Senate Intelligence Committee report gives gruesome accounts of waterboarding, sleep deprivation and starvation of prisoners.

Yet in 2006, Bush said, "I want to be absolutely clear with our people and the world: The United States does not torture. It’s against our laws, and it’s against our values. I have not authorized it, and I will not authorize it."

The Senate report notes that his speech, which is mentioned several times in the summary, was "heavily vetted" by the CIA. The report says Bush's remarks "contained significant inaccurate statements" regarding the effectiveness of the CIA's enhanced interrogation techniques.

The 2006 speech also marked the first official acknowledgment of the existence and use of CIA secret prisons, or "black sites," in the war against terror.
