Though John McCain, who was tortured in Vietnam, was highly offended by Zero Dark Thirty, apparently he isn’t against making light of the topic himself. At a press conference today, McCain joked about the possibility of Lindsey Graham being taken hostage in Afghanistan, then made a quip about using enhanced interrogation techniques during John Kerry’s upcoming hearing before the Senate Foreign Relations Committee. “We will look forward to interrogating him at his hearing next week, mercilessly,” said McCain. “We will bring back, for the only time, waterboarding, to get the truth out of him.” John Kerry’s “Mr. President” burn was pretty hilarious, but their joke war is officially getting out of hand.
