President Donald Trump endorsed South Carolina Lt. Gov. Pamela Evette for governor on Friday, throwing his weight behind a direct rival to Rep. Nancy Mace in the crowded June 9 Republican primary, and sending the clearest signal yet that defying him on the Jeffrey Epstein files carries a political cost.

Trump called Evette "an America First Patriot who has been with me from the very beginning" in a Truth Social post Friday afternoon. He praised her as the only gubernatorial candidate to endorse his 2024 presidential campaign at launch. "She crisscrossed South Carolina and other States for me, and I said, at the time, that this is truly something which I cannot forget!" Trump wrote.

The endorsement did not mention Mace by name. It didn't have to. Mace was one of four House Republicans who broke with Trump in the summer of 2025 by signing a Democrat-backed discharge petition to force a floor vote on releasing unredacted Epstein files. Trump has now endorsed against, or threatened to endorse against, every one of those four lawmakers.

Mace responds: 'If this is the price, I will never pay it'

Mace, for her part, did not grovel. In a statement posted to her campaign site, she acknowledged the political reality head-on.

"I have enormous respect for President Trump and everything he has done for our country and for South Carolina. That respect is genuine and it is unchanged."

But she drew a firm line on the Epstein question, framing her push for transparency as a matter of personal conviction and justice for abuse survivors.

"I also know I put the likelihood of an endorsement on the line when I demanded transparency on the Epstein files. I demanded it because you deserved the truth, ALL OF IT, and as a survivor, I had to get justice for these women. If this is the price of an endorsement, I will never pay it."

Her campaign referred the Daily Caller News Foundation to that statement when asked for further comment.

A pattern of consequences for the Epstein breakaways

Mace is the latest, but not the last, of the four Republican signatories to face consequences. The pattern is now unmistakable.

Thomas Massie, the Kentucky congressman who co-led the discharge petition effort, lost his May 19 primary to Trump-endorsed former Navy SEAL Ed Gallrein by nearly 10 points. That contest became the most expensive House nomination race in U.S. history. Massie had also clashed with the president over Iran policy and the One, Big, Beautiful Bill Act, but the Epstein petition was the flashpoint.

Former Georgia Rep. Marjorie Taylor Greene, another signatory, resigned from Congress in November 2025, one week after Trump withdrew his support and vowed to back a primary challenger. The message was received.

Colorado Rep. Lauren Boebert, the fourth signer, drew a public threat from Trump in mid-May after she campaigned for Massie against Gallrein in Kentucky. Trump floated backing a primary challenger against her as well.

Four members signed the petition. One has already lost his seat. One resigned. Two more now face the president's opposition. Whatever one thinks of the underlying policy dispute, the political arithmetic is blunt.

Trump's own reversal on the Epstein files

The irony embedded in this saga is worth noting. In November 2025, Trump reversed his earlier opposition to releasing the files. He called on House Republicans to make them public, writing that "we have nothing to hide, and it's time to move on from this Democrat Hoax." Days later, he signed the Epstein Files Transparency Act after Congress passed it by a near-unanimous margin.

So the files were released, with Trump's signature. The policy outcome the four breakaway Republicans demanded ultimately became law. But the method they chose, a discharge petition backed primarily by Democrats, crossed a line the president did not forget.

That distinction matters in understanding Trump's approach. His endorsement still carries enormous weight in Republican primaries, and he wields it to reward loyalty and punish defiance on process as much as substance.

The South Carolina governor's race: a five-way scramble

Trump's endorsement lands in a genuinely competitive field. Incumbent Republican Gov. Henry McMaster, who took office in 2017, is barred from seeking reelection due to term limits. McMaster endorsed Evette back in February.

A Trafalgar Group poll conducted May 21, 24, before Trump's endorsement, showed a tight race. Evette led with 19.9%, followed by Attorney General Alan Wilson at 19.4%, businessman Rom Reddy at 19.0%, Rep. Ralph Norman at 15.9%, and Mace in fifth place at 14.6%.

That pre-endorsement fifth-place standing is itself notable. Mace entered the race as perhaps the best-known candidate nationally, yet she trailed four rivals in her home state. Trump's backing of Evette could widen that gap considerably with the June 9 primary just days away.

Trump also pointed to speculation that Evette might tap McMaster's son, Henry McMaster Jr., as her running mate, calling it "A BIG added plus for Pam." If elected, Evette would become South Carolina's second female governor and its first Catholic governor.

Norman, meanwhile, has the endorsement of former Gov. Nikki Haley, who backed his gubernatorial bid after Norman supported her unsuccessful 2024 presidential campaign. Trump has shown a willingness to intervene decisively in Republican primaries across the country, and the South Carolina race is now another test of whether his endorsement can push a frontrunner over the top.

Mace's Epstein record and the timing problem

Whatever her standing in the polls, Mace has built a substantial record on Epstein transparency. Beyond the discharge petition, she led a House Oversight Committee push in March to compel then-Attorney General Pam Bondi to testify before Congress about the Justice Department's release of the files. She has framed the issue as personal, citing her experience as a survivor of sexual assault.

But the timing of her social media activity on Friday underscored the political tension. Hours before Trump issued his endorsement, Mace posted on X: "Pamela Evette is NOT ENDORSED by DONALD TRUMP. Do not believe her LIES." That post remained live as of late Saturday morning, a conspicuous artifact of how quickly the ground shifted beneath Mace's campaign.

Mace's broader political trajectory illustrates a tension other Republican lawmakers have faced when they break with the president on high-profile votes. The question is not always whether the underlying position has merit. It is whether the method of dissent, particularly allying with Democrats on a procedural maneuver, triggers a response that overwhelms whatever policy victory follows.

What the endorsement means for June 9

The South Carolina GOP primary is now a referendum on two things: who can govern the state, and who has Trump's blessing. In a five-way race where no candidate cracked 20% before the endorsement, Trump's backing gives Evette a structural advantage that polling alone cannot capture. His endorsement reshaped the Kentucky primary in decisive fashion. It cleared the field when Greene read the writing on the wall. Republican officeholders facing political pressure from the White House have learned that the consequences are not theoretical.

Mace may still run a competitive race. She has name recognition, a compelling personal story, and a policy record that resonates with voters who wanted the Epstein files released. But she is now running against the sitting president's explicit wishes in a Republican primary where his word carries extraordinary force.

The files got released. Trump signed the bill. The policy fight is over. But the loyalty question never expires, and in Republican primaries, that question still has only one right answer.
