(CNN) – As a former prisoner of war, Sen. John McCain, R-Arizona, is the only person in the Senate who has experienced torture.
He is also one of the few Senate Republicans backing the release of a torture report passed largely by Democrats in the Intelligence Committee.
"What I want to do is make sure that we never do it again, because it diminishes us as a nation and it diminishes us morally," McCain said in an interview with CNN's "The Lead with Jake Tapper."
The report detailed the CIA's brutal interrogation tactics against detainees captured after the September 11, 2001, attacks.
"I do not agree and do not support in any way using these, quote, techniques, unquote," McCain said.
The Arizona senator is skeptical that the tactics used even garnered useful information.
"From any experience with this kind of treatment that if someone is subjected to enough physical pain, that person will say whatever is necessary in order to make that pain stop, and that's why there's also a wealth of misinformation that comes out of people who are being subjected to it," said McCain.
