President Donald Trump trained his political weapons Saturday night on one of his own longtime Republican allies, publicly shaming Colorado Congresswoman Lauren Boebert and inviting challengers to run against her after she crossed into enemy territory to campaign for one of Trump’s most despised congressional critics.
The assault arrived via a series of Truth Social posts that stunned Republican circles, with Trump slapping Boebert with the label “Weak Minded Lauren Boebert” and openly soliciting someone — anyone — willing to step forward and challenge her in Colorado’s 4th Congressional District.
“Is anyone interested in running against Weak Minded Lauren Boebert in Colorado’s Fourth Congressional District?” Trump wrote.
The president did not stop there. He dug into Boebert’s 2024 decision to abandon Colorado’s 3rd Congressional District for the more reliably Republican 4th, a move she made after barely surviving her 2022 reelection.
“You remember Lauren moved to the District when it became obvious that she couldn’t win in her original Congressional District (The Third!) – A Carpetbagger, indeed!” Trump wrote.
Boebert’s offense, in Trump’s view, was her decision to travel to Kentucky and publicly stand beside Rep. Thomas Massie just four days before his May 19 Republican primary — a race Trump has invested enormous energy and resources into winning against the incumbent.
“Boebert is campaigning for the Worst ‘Republican’ Congressman in the History of our Country, Thomas Massie, of the Great Commonwealth of Kentucky,” Trump wrote, “and anybody who can be that dumb deserves a good Primary fight!”
Trump then placed his own prior endorsement of Boebert directly on the chopping block. He had backed her reelection in 2025, calling her “a MAGA warrior” and “an America First Patriot” — praise that now sits in sharp contrast to Saturday night’s assault.
“Even though I long ago endorsed Boebert, if the right person came along, it would be my Honor to withdraw that Endorsement, and endorse a good and proper alternative,” Trump wrote. “Just let me know, or announce your Candidacy, and I will be there for you!”
Saturday’s broadside against Boebert was not Trump’s first shot fired that evening. Minutes earlier, he had also targeted Kentucky Senator Rand Paul for appearing alongside Boebert at Massie campaign events.
“Word is that Rand Paul and Lauren Boebert, two very difficult, and highly unreasonable, Republican Votes, are right now in the Great Commonwealth of Kentucky, parading around like fools for the Worst ‘Republican’ Congressman in the History of our Party!” Trump wrote, again hammering Massie as a “disloyal, ungracious, and sanctimonious FOOL.”
Boebert fired back within 30 minutes, offering no apology and showing no signs of retreat.
“Yes, I saw the President’s post. No, I’m not mad or offended. I knew the risks when I agreed to stand by my friend Thomas Massie. I was, and will be, America First, America Always, and MAGA. Onward,” she posted.
The day before, Boebert had posted a side-by-side photo of herself with both men, staking out her position publicly before Trump’s response landed.
“He’s put his life on the line to save this great country,” she wrote of Trump. “I support both of these men. I’ve worked with both to preserve freedom and liberty. And if that makes you angry, bless your heart.”
The Kentucky primary at the center of this dispute has ballooned into the most expensive House primary race in American history, drawing $25.6 million in advertising spending, according to AdImpact.
Trump recruited and endorsed former Navy SEAL Ed Gallrein to take Massie’s seat, traveling personally to Kentucky in March to make his case to voters.
“Vote for Ed Gallrein, and wipe away the stench of one of the worst congressmen in the history of our great party, Thomas Massie,” Trump wrote Saturday night. “May we never have to deal with him again!”
Massie’s break with Trump spans several high-profile battles.
He voted against Trump’s signature tax-and-spending legislation in June 2025 over debt concerns, opposed Trump’s military strikes against Iran as unconstitutional, and led a push to release the Jeffrey Epstein files through a congressional discharge petition — a petition Boebert also signed, despite pressure from Trump to remove her name.
Massie has called Tuesday’s vote a “national referendum” on Trump’s clout within the Republican Party during his second term, describing it as “by far the most challenging reelection I’ve ever faced.”
Kentucky State Senator Gex Williams pushed back on the idea that voters must choose between the two men. “If you are thinking that you can’t be for President Trump and for Thomas Massie, you certainly can be,” Williams told attendees at a recent Lincoln Day Dinner in Covington.
Voters in Massie’s district remain divided. Retired law enforcement officer Steve Jarvis said he plans to oppose Massie for the first time despite previously supporting him.
“I understand voting your principle once or twice,” Jarvis said, “but at some point in time when it becomes crucial, I think they have to get in line.”
Registered nurse Jana Kathman said her vote stays with Massie.
“I just like him as a person, I like how he lives his life, and I know he stands very strong with his convictions,” Kathman said, while also criticizing Trump’s approach.
“I don’t like when Trump plays the little games as soon as someone opposes him, but we know that’s how Trump lashes out.”
Massie addressed the relentless pressure from the White House with a medical analogy.
“Once this race is over, I don’t think there’s any benefit to him attacking me,” he said. “I’ll have the antibodies from a natural infection.” He added: “This will be the booster shot.”
