In a speech shortly after launching his presidential bid in 2015, Trump countered criticism from McCain, a former prisoner of war in Vietnam, by saying, "I like people who weren't captured."

McCain has not been afraid to break from the president on key issues. Last summer, he quashed a Republican effort in the Senate to do away with the Affordable Care Act when he voted with the chamber's Democratic members opposed to the repeal.

More recently, McCain slammed Trump's congratulatory phone call to Russian President Vladimir Putin after his electoral victory, saying that "an American president does not lead the Free World by congratulating dictators on winning sham elections."
