At the “Jason Bourne,” premiere, actor Matt Damon told the Associated Press that he is “really frightened” of the prospect of presumptive Republican presidential nominee Donald Trump becoming the president of the United States.

After praising Senator Bernie Sanders’ (I-VT) endorsement of presumptive Democratic presidential nominee Hillary Clinton, Damon said, “I’m really frightened at the prospect of a Trump presidency and what that would mean. It’s not even a Republican-Democrat issue. I’m genuinely concerned about his temperament.”
