Republican National Committee Chairman Reince Priebus voiced confidence Friday that House Speaker Paul D. Ryan (Wis.) will eventually support presumptive Republican presidential nominee Donald Trump, and he pledged to play a leading role in brokering talks between the two Republicans.

Meanwhile, Trump said he was “surprised” by Ryan holding out on Thursday and that he plans to meet with him next week. The mogul argued that he brought a lot of new Republicans into the fold in the primaries and is building support in the party despite Ryan’s snub.

Speaking to journalist Mike Allen at a Politico Playbook Breakfast on Friday morning, Priebus, who is close with Ryan and has called for the party to rally behind Trump, said he thinks that the sudden exists of Sen. Ted Cruz (Tex.) and Ohio Gov. John Kasich from the race this week took the speaker by surprise and forced him to confront the prospect of Trump as the presumptive nominee sooner than he had anticipated. Ryan departed from his previous pledge to support the GOP nominee when he told CNN’s Jake Tapper on Thursday that he is “not there right now” with Trump.

“I think he’s going to get there,” Priebus said. “By the way, he wants to get there. It’s just that he wants some time to work through it.”

Priebus said Trump called him within minutes of Ryan’s interview and solicited advice for how to proceed.

“It wasn’t like furious or anything; it was just like, ‘What do I need to do?’ And so I said, ‘Listen — my view is just relax and be gracious, and I will talk to Paul and we will try to work on this.’”

The RNC chairman said a meeting could take place at his office or somewhere else to “start the process of unifying.”

In an interview broadcast Friday morning on Fox News Channel, Trump said Ryan’s decision was troubling, and he took credit for bringing “millions of people” into the Republican Party.

“I was surprised by it and by the way many other people were surprised by it, and some were really surprised by it and not happy about it. I will tell you, I have many endorsements from yesterday; they’re coming in left and right. He’s one of the only ones that really was surprising,” Trump said.

Trump said he expected to meet with Ryan on Wednesday. Ryan’s office has said he is happy to meet with Trump.

“I mean, to be honest, that’s a long time. There’s a lot of days before that. Look, my attitude is a lot of people say it’s a great thing. I don’t necessarily agree, but I can understand that point of view,” the mogul said.

Asked at the Politico event whether there is any way someone other that Trump could be nominated at the Republican National Convention in Cleveland, Priebus said it is “highly, highly doubtful,” but added, “Nothing’s impossible.”

Trump routinely disparages Democratic front-runner Hillary Clinton as “Crooked Hillary” at rallies. Priebus said Trump has done “an effective job of labeling” and that Clinton “does have a history of being crooked.”

Trump plans to campaign this weekend in the state of Washington. He has two afternoon rallies scheduled for Saturday.
