Donald Trump appeared to detonate a fresh MAGA civil war on Saturday night by publicly humiliating Lauren Boebert with a brutal new nickname while openly threatening to rip away his endorsement if a stronger challenger steps forward.

In a scorching Truth Social tirade, the president mocked the firebrand Colorado congresswoman as ‘Weak Minded Lauren Boebert’ while accusing her of betraying the MAGA movement by campaigning alongside one of his most bitter Republican enemies, Kentucky Congressman Thomas Massie.

The extraordinary public rebuke marked one of the sharpest attacks Trump has launched against Boebert, who was once considered among his fiercest allies.

The rant also signaled a dramatic escalation in the widening Republican feud surrounding Massie’s political future.

‘Is anyone interested in running against Weak Minded Lauren Boebert in Colorado’s Fourth Congressional District?’ Trump wrote in the blistering post.

The president then dredged up Boebert’s controversial district switch, mocking her move from Colorado’s 3rd Congressional District to the safer Republican-leaning 4th District after narrowly surviving reelection in 2022.

‘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.

But the real fury appeared centered on Boebert’s decision to campaign for Massie, the libertarian-minded Kentucky Republican who has become one of Trump’s top political targets heading into next week’s Republican primary.

Trump accused Massie of undermining Republican priorities and painted Boebert’s support for him as political treason. 

‘Boebert is campaigning for the Worst ‘Republican’ Congressman in the History of our Country, Thomas Massie, of the Great Commonwealth of Kentucky,’ Trump raged, ‘and anybody who can be that dumb deserves a good Primary fight!’

Then came Trump’s political threat that sent shockwaves through MAGA world.

‘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 warned.

‘Just let me know, or announce your Candidacy, and I will be there for you!’

The explosive post landed only minutes after Trump unleashed another furious broadside targeting both Boebert and Kentucky Senator Rand Paul for appearing at events supporting Massie.

‘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.

The president once again tore into Massie personally, branding him a ‘disloyal, ungracious, and sanctimonious FOOL.’

Vowing to unseat Massie, his ​quest poses a test for his hold on the Republican Party.

Massie has said Tuesday’s election serves as a ‘national referendum’ on Trump’s influence in his second term and whether the Republican Party can survive without the president.  

Trump has thrown the full weight of his political machine behind Massie’s primary challenger, former Navy SEAL Ed Gallrein, whom he described Saturday as ‘a true American Patriot, a Farmer from Kentucky, and a Military Hero.’

Trump unleashed two back-to-back Truth Social rants on Saturday night, attacking Lauren Boebert, Rand Paul and Thomas Massie in some of his most explosive anti-GOP posts

‘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. ‘May we never have to deal with him again!’

Within half an hour of Trump’s post, Boebert responded calmly with one of her own. 

‘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.’

On Friday she also posted a side-by-side photo of her standing with Trump and with Massie as she argued how she could support both men, notably calling Trump ‘a friend’.

‘He’s put his life on the line to save this great country,’ Boebert wrote. ‘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.’ 

Trump endorsed Boebert’s re-election in 2025, calling the Colorado congresswoman a ‘MAGA warrior’ and ‘an America First Patriot.’ 

It was the fourth election cycle that Boebert won the president’s endorsement, but her support for Massie now seems to have been enough to break their years-long alliance.

The increasingly personal feud between Trump and Massie has become one of the most dramatic intraparty battles of Trump’s second term.

Massie infuriated Trump by opposing parts of the president’s signature legislative agenda, including his massive tax-and-spending package. 

He has also pushed for the release of the Jeffrey Epstein files and criticized Trump’s military action against Iran.

Trump, meanwhile, has repeatedly savaged the Kentucky congressman with insults, previously calling him a ‘moron,’ a ‘nut job’ and a ‘third rate Grandstander.’

The president even traveled to Kentucky to campaign against Massie in an unusually direct attempt to purge one of the GOP’s most stubborn independent voices.

But despite Trump’s relentless attacks, Massie still retains a loyal base of support in Kentucky’s deeply Republican 4th Congressional District, where voters have repeatedly reelected him since 2012.

At a recent Lincoln Day Dinner in Covington, Kentucky State Senator Gex Williams urged Republicans not to view the race as a choice between Trump and Massie.

‘If you are thinking that you can’t be for President Trump and for Thomas Massie, you certainly can be,’ Williams told attendees.

The showdown has split Republican voters across the district.

Tonya Young, a 57-year-old special education teacher who attended the dinner, admitted she was torn between loyalty to Trump and support for Massie’s independent streak.

‘Sometimes you have to just bite the bullet and compromise on things,’ Young told the Associated Press.

Another voter, retired law enforcement officer Steve Jarvis, said he planned 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.’

Others remain firmly behind Massie despite Trump’s attacks.

Registered nurse Jana Kathman said she still intended to vote for the congressman even when she disagreed with him politically.

‘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 told the AP.

She also criticized Trump’s combative style toward Republicans who oppose him.

‘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,’ she said.

Massie has tried to project calm amid the escalating political assault.

The congressman has described the race as ‘by far the most challenging reelection I’ve ever faced.’

Still, he expressed hope that Trump’s anger would eventually cool after the primary battle concludes.

‘Once this race is over, I don’t think there’s any benefit to him attacking me,’ Massie said. ‘I’ll have the antibodies from a natural infection.’

After years of surviving political fights within the Republican Party, Massie joked that perhaps he already had some immunity built up.

‘This will be the booster shot,’ he said.
