Former Vice President Dick Cheney says he has "no regrets" about the harsh interrogation policies the Bush administration pursued in the wake of the September 11, 2001, terror attacks.
The often controversial Cheney also says "I don't know why" former President George W. Bush should feel betrayed by insider information he reveals in his new memoir.
Asked in an NBC interview if he still embraces waterboarding, Cheney says, "I would strongly support using it again if circumstances arose where we had a high-value detainee and that was the only way we could get him to talk."
The new book will be published next week by Simon & Shuster. Cheney was a lightning-rod for criticism during Bush's presidency, accused by opponents of often advocating a belligerent US stance in world affairs.
