"I still, at this moment, continue to intend to support the Republican nominee, but it's getting harder every day," Sen. Marco Rubio told reporters when asked about GOP presidential front-runner Donald Trump.

"You can't say tonight that you can make that pledge," Fox News' Bret Baier asked at the first GOP debate

"I cannot say I have to respect the person if it's not me, the person that wins," Trump answered. 

To stop that, the Republican National Committee had candidates sign a pledge to support the GOP nominee, no matter what.

So despite Rubio's personal beliefs, he will have to support a Trump GOP nomination.
