Republican Senator John McCain may be on the same side of the aisle as President-elect Donald Trump, but when it comes to Trump's position on torture -- he has a few words of warning.
According to the Associated Press, McCain told a crowd during a panel discussion at the annual Halifax International Security Forum on Saturday, "We will not waterboard," regardless of what "the president of the United States wants to do or anybody else wants to do."
He added, "We will not torture people ... It doesn't work."
