Donald Trump, though leading in delegates and votes in the Republican presidential candidate race, doesn't like the "delegate math" that could let Ted Cruz (or someone else) take the nomination at the party's convention this summer.
Trump criticized the delegate selection process as undemocratic and said the RNC will face a "rough July" if he's denied the nomination.
"I hope it doesn't involve violence. I hope it doesn't. I'm not suggesting that," Trump told reporters Sunday in Staten Island. "I hope it doesn't involve violence, and I don't think it will. But I will say this, it's a rigged system, it's a crooked system. It's 100 percent corrupt."
Reince Priebus, the chairman of the National Republican Committee, has told his colleagues not to consider making changes to the rules that govern the convention's nomination process.
