According to the 6,300-paged report -- which officials discussed with the Post only on the condition of anonymity -- CIA detainees were subject to severe and "excruciating" interrogation methods for the sake of little to no significant information.

“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,” one U.S. official said. “Was that actually true? The answer is no.”

The report also details a lack of unity within the CIA program. It describes one particular incident in Thailand where intelligence workers walked out of a secret CIA prison after being bothered by the extreme measures being employed there.

Critics of the report say it reflects biases from the FBI, as some of its authors are former FBI agents and analysts. 

The committee will vote Thursday to send an executive summary to President Obama. Parts of the report will then be declassified and later released to the public.
