Chris Christie Explains to Jimmy Fallon His 'Hostage' Look at Trump Event

"If you're used to talking, it's awkward not to talk," he said.

Fallon also asked Christie, 53, why he is supporting Trump over Ted Cruz or John Kasich.

"Because he's better than them," he said, without elaborating.

Christie also jokingly responded to a question about being Trump's running mate.

"I have a hard time believing that anyone would ask me to be vice president," he said, pointing to a cardboard cutout of himself next to him. "When you're vice president, that's basically what you do, right?"

Looking ahead at his post-governor plans, Christie said, "When the governor thing is over, I'd maybe like to play tambourine in The Roots," referring to the late-night show's house band.
