Reince Priebus defended the GOP nominating process tonight as a firestorm continues after Donald Trump lambasted the Colorado state contest for being “rigged.”

The Republican presidential front-runner slammed the GOP nominating process on Fox and Friends on Monday, after Ted Cruz completed his sweep of the state's 34 delegates without any votes being cast by citizens in a traditional primary process.

“There’s nothing mysterious about this,” the Republican National Committee chairman said On the Record.

“It’s the same process they used four years ago,” he told Greta Van Susteren.

“It’s no different. Some states use a primary system to bind delegates, some states use a caucus system to bind delegates, and some states use a convention system to bind delegates.”

Greta pointed out that the rules in the Colorado election are decided by the Colorado Republican Party, not the RNC.

“That’s right,” said Priebus. “This isn’t something that just happens over one day. This is an organizational process that candidates have to be involved with from the very beginning.”
