Matt Damon on Donald Trump Possibly Being President: 'It Makes Me Nervous'

"I'm kind of amazed we've arrived at this point," Damon said of Trump's run.

Damon said he always saw Trump as "very entertaining," but he never saw him in a presidential light.

"I'm kind of amazed we've arrived at this point," he said of the businessman's nomination for president. "I'm concerned."

"Trump actually could win," he said. "I don't think he has the temperament. I have a lot of Republican friends and a lot of my Republican friends I wish were the Republican nominee."

Damon added that he believes the "rigging" of the election system led Trump to become the Republican nominee.

"It makes me nervous," he said. "It's a binary choice.... There's no way we can let this guy be the [president]. To let that dude have the nuclear football, are you kidding me? That's dangerous. He's impulsive and rash, and doesn't seem to think deeply about too many things."

Suffice it to say, Damon says he is voting for Clinton.

"That's the real deal!" Travers said.

Damon said hearing that was "fantastic" and that he would hop on the phone with his acclaimed director the second he left the building.

"Jason Bourne" opens in theaters tomorrow.
