Chris Christie: “The problem is they don't want to do the hard work that's necessary to lead and change the party.”

The one commitment I will make to you this morning is I'm not voting for Donald Trump under any circumstances.

I want to see who gets elected. You look at folks like Mike Lawler in New York or Mark Molinaro in New York. Those are the kind of Republicans who will be responsible about certifying an election.

It's clear to me tonight that there isn't a path for me to win the nomination, which is why I'm suspending my campaign tonight for the United States.

Mr. Trump has the opportunity to rein in some of the worst rhetorical impulses of the Republican Party.
