The report, built around detailed chronologies of dozens of CIA detainees, documents a long-standing pattern of unsubstantiated claims as agency officials sought permission to use — and later tried to defend — excruciating interrogation methods that yielded little, if any, significant intelligence, according to U.S. officials who have reviewed the document.

 

“The CIA described [its program] repeatedly both to the Department of Justice and eventually to Congress as getting unique, otherwise unobtainable intelligence that helped disrupt terrorist plots and save thousands of lives,” said one U.S. official briefed on the report. “Was that actually true? The answer is no.”
