Republican presidential candidate John Kasich in an interview early Sunday said rival Donald TrumpDonald John TrumpClinton takes swipe at 'false equivalency' in media coverage of 2016 election Trump asked Netanyahu if he actually cares about peace: report Official: Trump to urge North Korea to dismantle nuclear program in return for sanctions relief MORE’s prediction of riots if the GOP front-runner is not the party’s nominee was “inappropriate” and “outrageous.”

"When he says that there could be riots, that's inappropriate," the Ohio governor said during an interview for CBS’s “Face the Nation.”

“While we have our differences and disagreements, we're Americans. Americans don't say, 'Let's take to the streets and have violence.'"

"I think we'll win before getting to the convention,” Trump said last week on CNN. “And if we're 20 votes short or if we're 100 short, and we're at 1,100 and somebody else is at 500 or 400 ... I don't think you can say that we don't get it automatically."

"I think you'd have riots," Trump continued. "I'm representing ... many, many millions of people, in many cases first-time voters."

"I wouldn't lead it, but I think bad things would happen,” he added.

"I don't even want to use the word 'riots' or 'violence,'" Kasich said in the CBS interview. "That's inappropriate. Our kids are watching. Now ... that doesn't mean I'm not running a positive campaign, but those kind of comments are way out of bounds. Frankly, they're outrageous."

Kasich also said that reported threats against Trump’s family were “terrible.”

"That is not America. This is all fringe, and the American people want to see progress. They want to see us unified as a nation. That's what they're hungry for. That's what I'm trying to do," he said.
