Hours after House Speaker Paul Ryan refused to embrace Trump, Priebus, who has appealed for GOP unity, acknowledged that significant gaps remain between Trump and the Republican Party on policy and style. Priebus said the GOP does not endorse Trump’s call for a temporary ban on Muslim immigration and said Trump must adjust the way he presents himself to the Latino community.

“It’s not something that I believe in or our party believes in,” Priebus said of the Muslim ban. “I believe our party is the party of the open door. Our party is the party of opportunity and freedom and equality and it always will remain such.”

A longtime Ryan ally, Priebus said he thought the Speaker was “being honest about how he feels” about Trump, while expressing confidence that Ryan will ultimately back the party’s nominee. He added that he is helping to broker a meeting between Ryan and Trump next week to start bridging the divide. Trump called Priebus within minutes of Ryan’s critical comments Thursday to express concern and to discuss how to best win Ryan over.

Speaking at a Politico breakfast in Washington, Priebus said Donald Trump is not the head of the Republican Party. “It’s the party’s party,” he said.

Priebus said he believes Trump understands that he has to adjust his tone for the general election, saying that behind closed doors Trump is “far more gracious and personable than I think you see at rallies.”

“You also need to have the tone at the top that people obviously believe that you like them,” Priebus said of reaching out to minority voters. “Because if they don’t think you like them, they aren’t going to vote for you. I think there’s work to do. I think there’s work on tone to do. I’ve been clear about that.”

Asked about Trump’s tweet of a taco bowl on Cinco de Mayo, which provoked an internet backlash, Priebus said he thinks that was an effort on Trump’s part to broaden his appeal.

“He’s trying,” Priebus said with a laugh. “Honestly I think he’s trying. And I honestly think he understands that building and unifying and growing the party is the only way we’re going to win.”

Acknowledging that many conservatives are still wary of his nomination, Priebus said it would be a “smart thing” for Trump to release five to 10 names he would consider for the Supreme Court to allay those concerns.

Reflecting on the nominating process, Priebus said he believes that in the next cycle the RNC will have “even more control” of the system. After taking over the debate calendar in unprecedented fashion, Priebus said he’d like to move to a system where the party owns the rights to the nominating process and sells them to television networks like professional sports leagues. Priebus, who has served three consecutive terms as RNC chairman, didn’t rule out seeking a record fourth term in January.
