His comments came with Super Tuesday results indicating Trump would win as many as eight states. They also came a week after Graham joked, “If you killed Ted Cruz on the floor of the Senate, and the trial was in the Senate, nobody could convict you.”
Graham has been a tough critic of both Trump or Cruz. He once said that choosing between the two would be "like being shot or poisoned. I think you get the same result, whether it's quick or it takes a long time."

"I think we're about ready to lose to the most dishonest politician in America, Hillary Clinton, and how could you do that? Nominate somebody who's crazy. And I think dishonest beats crazy, that's our problem," Graham said.
"And Donald Trump I think is crazy — the things he says."
Graham said nominating Trump would be a major setback to GOP efforts to attract more Hispanic voters.
"You'll never convince me that Donald Trump is the answer to the problem we have with Hispanics.
