Trump Doesn't Expect Violence if He Fails to Win Republican Presidential Nomination

He continued his complaints after the RNC's "rigged system" to pick a nominee.

"I hope it doesn’t involve violence," he said, claiming his rallies are "the safest places to be in the country."

"But I will say this -- it's a rigged system, it's a crooked system. It's 100 percent crooked."

Trump expressed confidence he would win the nomination on the first ballot in Cleveland by securing the needed 1,237 delegates.

"A lot of people say, 'don’t complain, you’re winning,' and I think we’ll get there on the first ballot, actually," he said.

"We didn’t play in Colorado because I heard that it was going to be for the bosses, for the RNC," he said. "I don’t wanna play that game. I’m winning with the voters and we’re winning big."

Trump contended Cruz's recent wins were because of the money his campaign spent wining and dining delegates.

"Nobody has better toys than I do," he said. "I can put them in the best planes and bring them to the best resorts anywhere in the world. Doral, Mar-a-Lago. I can put them in the best places in the world -- California. I have something that blows everything away."

Trump’s campaign has accused the Cruz campaign of breaking the rules when it comes to the hunt for the delegates needed to secure the nomination. His convention manager, Paul Manafort, threatened the campaign would be challenging some results while speaking to ABC's "This Week" on Sunday.

“We’ll be filing protests. Missouri, we're going to be filing protests. Colorado, we're going to be filing protests,” Manafort said.

Cruz’s delegate operations director, Ken Cuccinelli, countered in a later interview, saying Trump's campaign was whining about the results and had used unsavory tactics to win delegates.

“How about calling for riots in the street? How about threats -- 'We’re going to go to the hotel rooms of delegates' -- death threats to the Colorado Republican chairman?” Cuccinelli said. “They keep using the rhetoric. This is a banana republic approach from the Trump team because they’re getting beat on the ground.”
