President George W. Bush indicated in his memoir that he approved CIA interrogation tactics

“CIA experts drew up a list of interrogation techniques that differed from those Zubaydah had successfully resisted. George [Tenet] assured me all interrogations would be performed by experienced intelligence professionals who had undergone extensive training. Medical personnel would be on-site to guarantee that the detainee was not physically or mentally harmed.

“At my direction, Department of Justice and CIA lawyers conducted a careful legal review. They concluded that the enhanced interrogation program complied with the Constitution and all applicable laws, including those that ban torture.” (George W. Bush, Decision Points, 2010, p. 169)
