President Donald Trump threatened to withdraw his endorsement of U.S. Representative Lauren Boebert on May 16, 2026, after the Colorado congresswoman campaigned for Representative Thomas Massie of Kentucky.

The president used Truth Social to call for a primary challenger to run against Boebert in Colorado’s Fourth Congressional District, signaling a break with the hardline conservative who had previously been a staunch ally.

The tension began after Boebert made campaign appearances for Massie, a Republican who has frequently clashed with the president over major legislation and the Iran war.

In a post on Truth Social, Trump criticized Boebert’s decision to support Massie, whom he described as the Worst ‘Republican’ Congressman in the History of our Country.

Trump wrote that anybody who can be that dumb deserves a good Primary fight!

Conflict Over Representative Thomas Massie

The friction between President Trump and Representative Massie extends beyond legislative disagreements. Massie has led a drive within the Republican party to release government files concerning the late financier and convicted sex offender Jeffrey Epstein.

This effort to uncover government records, combined with Massie’s defiance of the president on other key issues, has led Trump to vow to unseat the Kentucky representative.

Massie is currently facing a Republican primary in Kentucky on May 19, 2026. He is running against Ed Gallrein, a retired Navy SEAL who has received the endorsement of President Trump.

Call for Primary Challengers in Colorado

Following Boebert’s support for Massie, the president actively sought candidates to challenge her in her own district.

Trump specifically asked if anyone was interested in running against Weak Minded Lauren Boebert in Colorado’s Fourth Congressional District.

He encouraged potential candidates to announce their candidacy or contact him, stating, Just let me know, or announce your Candidacy, and I will be there for you!

The president’s public effort to unseat Massie and his threat to drop his support for Boebert serve as a test of his influence and hold over members of the Republican Party.
