House Speaker Paul Ryan said Monday that he would do “whatever” Donald Trump asks at the July Republican convention in Cleveland — including stepping down as chairman.

“He’s the nominee. I’ll do whatever he wants with respect to the convention,” Ryan told the Milwaukee Journal Sentinel three days before a planned sit-down with the presumptive GOP nominee.

But Ryan also said he hoped the meeting resulted in a bromance with Trump — and stressed that the speaker’s bombshell comment last week that he wasn’t ready to back the Manhattan tycoon wasn’t his final say on the endorsement.

“I just want to get to know the guy … we just don’t know each other,” Ryan said.

“I never said never. I just said [not] at this point. I wish I had more time to get to know him before this happened. We just didn’t.”

He also told the paper that he was not withholding his endorsement because he was planning a run for the White House in 2020, as Sarah Palin charged over the weekend.

“I would not have become speaker of the House if I had 2020 aspirations. If I really wanted to run for president, I could have run in 2012 and 2016. The speaker is not exactly a good steppingstone for president. I think people who know me know that is not my aspiration,” Ryan said.

Palin also vowed to support Paul Nehlen, a pro-Trump Republican challenging the speaker in a primary.

But Trump distanced himself from Palin’s remarks.

“She’s a terrific person, but she’s very much a free agent and I didn’t know about this until yesterday,” Trump said on CNN.

“I guess she’s been fighting, or she’s endorsing somebody that’s running against Paul Ryan, and I didn’t know about it until yesterday when I read about it.”

Ryan said if a third-party conservative candidate entered the race for president, it “would be a disaster for our party. I have communicated that to plenty of people,” and that his reluctance to back Trump at this point was a move to avoid “fake” unity instead of genuine unity.

“We have right now a dis-unified Republican Party. We shouldn’t sweep it under the rug without addressing it. That would be to our detriment in the fall,” the Wisconsin rep said, declining to say much more about Trump until they meet.

“I don’t want to have a conversation with Donald Trump through the media. I want to have a straight conversation with Donald Trump on behalf of the party, myself, too. Let me say this, the man deserves a ton of credit for an amazing achievement, which is to bring millions of people into this party and to have a very impressive victory … At the same time, we want to make sure we don’t pretend we’re unified and then go into the fall at half strength,” he said.

“I believe between now and July we will be able to figure out how to unify our party.”

One source suggested the real issue between Trump and Ryan is money.

“Ryan’s first, second and third priority is to keep the Republican majority in the House. It’s all about the money. Why would Ryan support Trump without reaching an understanding about how much fundraising will be targeted toward House races? There has to be coordination.”

Trump also backpedaled Monday from weekend statements that he’d raise taxes on the wealthiest Americans.

Trump told CNN and the Fox Business Channel that his tax plans would be across-the-board cuts to everyone — but that he might have to restore some of the cuts he wants to give to the wealthy.

“I put in the biggest tax decrease of anybody running for office by far, OK? And many people think it’s great and if anything, I was criticized because it’s too deep, it’s too steep a cut,” he told CNN.

“That really is a proposal because we have to go to Congress, we have to go to the Senate, we have to go to our congressmen and -women and we have to, you know, negotiate a deal,” he said.

“Now if I increase it on the wealthy, that means they’re still going to pay less than they pay now. I’m not talking about increasing from this point. I’m talking about increasing from my tax proposal.”

Meanwhile, Trump on Monday named New Jersey Gov. Chris Christie to head up his “transition team” as he gears up for the general election against expected Democratic nominee Hillary Clinton.

Christie, one of the first mainstream Republicans to endorse Trump, will be “overseeing an extensive team of professionals preparing to take over the White House, and all that entails, in the fall,” Team Trump announced in an optimistic statement.

“Governor Christie is an extremely knowledgeable and loyal person with the tools and resources to put together an unparalleled transition team, one that will be prepared to take over the White House when we win in November,” Trump said.

Christie lauded his new boss in the statement.

“I am honored by the confidence being placed in me by Mr. Trump and look forward to putting together a first-rate team to assemble an administration to help best serve the president-elect and the nation,” the New Jersey governor said.
