It's time to support Donald Trump or "just shut the hell up," according to one of the presumptive Republican nominee's campaign co-chairs and policy advisers.

"I think from our perspective from the campaign, many of us have the scars of going out and running campaigns where we've had to run against the tide," Sam Clovis remarked on CNN's "New Day." "We've run against the establishment. We've had to fight the establishment, the establishment has come in and outspent us. The establishment has control of the media, a lot of these other issues and some of us have been successful, others not so much."


Republican Party leadership needs "to figure out what they want," Clovis said, a day after Trump remarked at a rally in Atlanta that either the party needs to "get tougher," adding that although running for president is "too tough to do it alone ... I think I'm gonna be forced to."

"Either they want to get behind the presumptive nominee who will be the nominee of this party and make sure that we do everything we can to win in November or we're just asking them if they can't do that, then just shut the hell up," Clovis said. "That's what we're asking them to do."

CNN's Chris Cuomo then said that Republicans' response would be that Trump should stop making controversial remarks that jeopardize the party in both the presidential election and in down-ballot races.

"Well, I think you need to go to the rallies that are there and look at the people that come to those rallies. We have broadened" the party, Clovis said. "We've brought out millions more people to vote. People who have not ever been part of this, so I'm really struggling with that argument to come out here. What I think is still going on and you and you and I talked about this many times, Chris is that there is a push that pushes Mr. Trump into a particular template."

The Republican establishment has "always wanted" control of the party's nominee, Clovis added.

"So it's either the leadership that's wrong or we're wrong. And it can't be both. And I think right now we're the ones that are winning. They're not," Clovis said. "They haven't done anything to stop the expansion — let me finish this. They haven't done anything to stop the expansion of government. They haven't done anything to work toward the balancing of the budget. They have gutted the military and they've done nothing to protect the cultural values of this country. So I'm really tired of the Republican establishment coming out and shooting their mouths off and talking about how we need to comport with them. That's not the way this works. We're the people, we're going to win this election."
