The three former CIA directors George Tenet, Porter Goss, and Michael Hayden, who had supervised the program during their tenure, objected to the Senate Report in a Wall Street Journal op-ed piece, calling it poorly done and partisan. They insisted that some information derived from the CIA program was useful, specifically that interrogation techniques made some detainees compliant and that the "information provided by the totality of detainees in CIA custody" had led to Osama Bin Laden. According to the CIA, enhanced interrogation "conditions" were used for security and "other valid reasons, such as to create an environment conducive to transitioning captured and resistant terrorist (sic) to detainees participating in debriefings."
