I don't give a damn what the president of the United States wants to do. We will not waterboard.
Republican Sen. John McCain took aim at President-elect Donald Trump over his vow to "bring back a hell of a lot worse than waterboarding."
McCain, chairman of the Senate Armed Services Committee, said any attempt by Trump to reinstate waterboarding or other harsh interrogation techniques, would be challenged in court "in a New York minute."
"I don’t think it’s tough enough."
Trump said during the campaign that he plans to use harsher measures against suspected terrorists, including waterboarding.
CIA's techniques were "brutal" and "ineffective"
A bipartisan 2014 Senate report examining interrogation methods endured by CIA prisoners found that torture, including rectal feeding and sleep deprivation, is ineffective and "regularly resulted in fabricated information."
Some Congressional Republicans rejected the report's conclusion that torture didn't produce valuable intelligence. In their own 167-page report, they argued the CIA's interrogation program "saved lives and played a vital role in weakening al Qa-ida."
Torture is illegal under both the Geneva Conventions and U.S. law.
Last year, President Obama signed legislation limiting interrogation techniques to what's outlined in the U.S. Army Field Manual.
Trump's pick for CIA director backs waterboarding
According to Politico, Republican Representative Mike Pompeo "has defended Bush-era interrogation programs that included waterboarding and other techniques."
Earlier this year, current CIA Director John Brennan suggested he would resign should the new president bring back waterboarding: "I’m not going to be the director of CIA that gives that order. I think they’re going to need to find another director."
