The Torture Memos, sometimes called the Bybee Memo or 8/1/02 Interrogation Opinion, were a set of legal memoranda drafted by Deputy Assistant Attorney General of the United States John Yoo and signed by Assistant Attorney General Jay Bybee. They advised the Central Intelligence Agency, the United States Department of Defense, and the President on the use of mental and physical torment and coercion such as prolonged sleep deprivation, binding in stress positions, and waterboarding, and stated that acts widely regarded as torture might be legally permissible under an expansive interpretation of Presidential authority during the "War on Terror." These memoranda have been the focus of considerable controversy, and were repudiated by President Barack Obama in early 2009.
The "torture memos" include three documents entitled, "Standards of Conduct for Interrogation under 18 U.S.C. sections 2340-2340A," "Interrogation of al Qaeda" (both drafted by Jay Bybee), and an untitled letter from John Yoo to Alberto Gonzales.
