Former United States Vice President Dick Cheney says a damning report on CIA interrogations is "full of crap" and that he'd use the techniques again "in a minute".

Investigators accused the spy agency of inflicting pain and suffering on prisoners beyond legal limits and deceiving the nation with narratives of life-saving interrogations unsubstantiated by its own records.

Cheney, who served under President George W Bush during the period after 9/11, says the report, of which 500 pages of the 6,700-page long investigation have been released to the public, was deeply flawed.

"I think it is a terrible report, deeply flawed," Cheney told Fox News. "It's a classic example of where politicians get together and throw professionals under the bus."

"The notion that the agency was operating on a rogue basis was just a flat out lie."

He says enhanced interrogation techniques were legally justified and inconsistent with torture, although he did admit "rectal rehydration" was not an approved technique.

Asked if the end justifies the means when it comes to interrogation, he was unequivocal.
