Story highlights Kasich dismissed Trump's accusations that the GOP nomination process is "rigged"

"Act like you're a professional, be a pro," Kasich said

Washington (CNN) Ohio Gov. John Kasich dismissed Donald Trump's accusations that the GOP nomination process is "rigged," calling on the Republican front-runner to "act like you're a professional."

"You've got to have a certain number of delegates to be nominated," Kasich told CNN's Dana Bash in an interview aired Sunday on "State of the Union." "It's like saying I made an 83 on my math test so I should get an A just because I think it's rigged that you have to make a 90 to get an A."

"I mean, come on," Kasich continued. "Act like you're a professional, be a pro."

Kasich's comments came during a wide-ranging interview in which he also touched upon sexual assault on college campuses, big business and new religious freedom laws across the country.

He said he remained optimistic about the future of his campaign, reiterating that the road to the nomination is not solely about winning states.
