WASHINGTON — With his job in jeopardy, House Speaker Mike Johnson plans to head to Florida on Friday to meet with the one man who could save his precarious speakership: the presumptive Republican presidential nominee, former President Donald Trump.

Trump and Johnson, R-La., plan to deliver remarks about “election integrity,” said several sources, one of whom said the two Republicans will talk about legislation focused on preventing noncitizens from voting. That’s already illegal — and very rare — but Trump and many of his allies have falsely claimed that undocumented immigrants affected the 2020 election and warned they could do so this year.

“Congress has a role with regard to federal elections. We want to make absolutely certain that anybody [who] votes is actually an American citizen,” Johnson told reporters on Friday. “We need to make sure the federal law is clear on that matter, and make sure we actually have election integrity because it’s the biggest concern of the American people right now.”

Johnson is making a pilgrimage to Mar-a-Lago, Trump’s golf resort in Palm Beach, as he faces an ongoing threat to his job from Rep. Marjorie Taylor Greene, the far-right Georgia firebrand and Trump loyalist who has ratcheted up attacks on him less than six months into the job.

If Trump stays silent, Greene may see it as a sufficient opening. But she is unlikely to defy Trump if he pushes for Johnson to keep his job and pressures her not to force a vote to oust him, known as a motion to vacate.

“Obviously, it would help” Johnson if Trump reiterated his support for him, conservative Rep. Ralph Norman, R-S.C., who has criticized Johnson at times but doesn’t support the push to remove him, said in an interview.

“Trump has got a following; he’s our nominee. … It’s now Trump and Biden — there is no other choice. So it’s good that they’re getting together,” Norman continued, saying he expects Trump to impress upon Johnson that his No. 1 focus should be passing new restrictions on immigration.

Asked what Johnson has to gain by visiting Trump, Rep. Anna Paulina Luna, R-Fla., a Johnson critic, said, “President Trump has been a great negotiator, but also he has a lot of good insight into what the American people want,” adding that she looks forward to their announcement.

Johnson’s visit to Palm Beach comes just three days before Trump is set to stand trial in New York, accused of falsifying business records in connection with hush money payments to adult film star Stormy Daniels.

It will be the first in-person meeting between the two men since Trump became the Republican Party’s presumptive nominee. Such a meeting wouldn’t be unusual between a GOP speaker and a presidential nominee as the party unifies behind its candidate. But it comes exactly three weeks after Greene filed her motion to topple Johnson and as other conservatives grumble about his handling of a host of thorny matters.

Fueling the threats to Johnson’s job are two contentious issues on which he is boxed in: approving aid to Ukraine and renewing a warrantless surveillance program under Section 702 of the Foreign Intelligence Surveillance Act. In both cases, Johnson faces pressure from his party’s committee leaders, centrist Republicans and the Senate to act — against the wishes of a band of hard-right members who oppose both issues.

Greene, who released her motion last month before a two-week House recess, hasn’t triggered it yet. If she does, it would require a vote within two legislative days. Upon the House’s return, and despite pleas from colleagues to stand down, she has only ratcheted up her attacks on Johnson.

Greene issued her threat over the sweeping government funding bill that passed last month, claiming Johnson gave President Joe Biden and the Democrats “everything they wanted” in the spending package. (Johnson negotiated the bill, which included various conservative provisions, with the Democratic-controlled Senate and White House.)

“I will not tolerate our elected Republican Speaker Mike Johnson serving the Democrats and the Biden administration and helping them achieve their policies that are destroying our country. He is throwing our own razor-thin majority into chaos by not serving his own GOP conference that elected him,” Greene wrote in a letter to colleagues this week, while calling on Johnson not to fund aid to Ukraine or renew Section 702 without a new “warrant requirement.”

No other Republicans have said they would vote for Greene’s motion to vacate, and Greene downplayed the meeting Friday, saying, “President Trump meets with people all the time.”

Rep. Mario Diaz-Balart, R-Fla., a Johnson ally and Trump supporter, said he didn’t think the threat to the speaker was real: “Johnson is on very strong footing here, despite all the noise.”

And some Democrats have said they’d vote to protect Johnson if Republicans seek to oust him for passing Ukraine aid. Democratic leaders, who unified the conference last fall against protecting his predecessor as speaker, Kevin McCarthy of California, are keeping that door open with Johnson.

“If the speaker were to do the right thing and allow the House to work its will with an up-or-down vote on the national security bill, then I believe there are a reasonable number of Democrats who would not want to see the speaker fall as a result of doing the right thing,” House Minority Leader Hakeem Jeffries, D-N.Y., told reporters Thursday, adding that he was making an “observation, not a declaration, because we have to have a conversation.”

Friday’s meeting is reminiscent of McCarthy’s flying to Mar-a-Lago to make amends with Trump just weeks after McCarthy publicly castigated him for inciting the Jan. 6, 2021, riot at the Capitol. After Republicans took back control of the House, Trump endorsed McCarthy for speaker and helped him win the gavel amid a weeklong stalemate.

But last fall, when Rep. Matt Gaetz, R-Fla., a Trump ally, forced a vote to overthrow McCarthy, Trump stayed silent and made no effort to save him.

Johnson’s fate may be different given his role in Trump’s efforts to overturn Biden’s 2020 election victory. He led the amicus brief signed by more than 100 House Republicans that backed a Texas lawsuit seeking to invalidate the election results in four swing states Biden carried.
