US President Donald Trump repudiated Rep. Thomas Massie (R-KY) on Monday, calling him a “pathetic loser” after the Kentucky Republican criticized Trump’s weekend strike on Iranian nuclear facilities as unconstitutional.

Massie, a libertarian‑leaning congressman and a staunch opponent of American intervention in foreign conflicts, joined Democratic colleagues Sen. Tim Kaine (D-VA) and Rep. Ro Khanna (D-CA) on the CBS program “Face the Nation” to denounce the strikes on Iran. Massie lambasted Trump’s decision to authorize the military actions as an unconstitutional abuse of presidential power, claiming that there was “no imminent threat” to the US.

In response, Trump took to Truth Social, labeling Massie “not MAGA,” referring to the Make America Great Again movement of his supporters. Trump also accused the lawmaker of routinely voting “NO” and supporting Iran’s nuclear ambitions while the regime chants “Death to America.” Trump slammed Massie for supposedly not supporting his agenda.

“Congressman Thomas Massie of Kentucky is not MAGA … Actually, MAGA doesn’t want him, doesn’t know him, and doesn’t respect him,” Trump said.

“Massie is weak, ineffective, and votes ‘NO’ on virtually everything … He is disrespectful to our great military — not even acknowledging their brilliance and bravery in yesterday’s attack, which was a total and complete WIN,” Trump added.

Trump urged Kentucky Republicans to refrain from voting for Massie’s reelection, arguing that the representative has not been an effective lawmaker or advocate for the conservative legislative agenda. Massie has been an outspoken critic of several of Trump’s policies, including his “Big, Beautiful Bill.”

“MAGA should drop this pathetic LOSER, Tom Massie, like the plague! … GET THIS ‘BUM’ OUT OF OFFICE, ASAP!!!” Trump wrote on Truth Social.

The president continued, claiming that he would support a challenger to unseat the outspoken Kentucky representative.

“We will have a wonderful American Patriot running against him in the Republican Primary, and I’ll be out in Kentucky campaigning really hard.”

Close advisers of Trump have recently launched a new anti-Massie super PAC and are searching for the right candidate to challenge the incumbent representative, according to reporting by Axios.

Later on Sunday, Massie responded on X/Twitter that Trump “declared so much War on me today it should require an Act of Congress.”

Since the Palestinian terrorist group Hamas’s Oct. 7, 2023, invasion of Israel, Massie has been one of the few Republicans to consistently question US military and financial support for Israel. He opposed multiple House resolutions condemning Hamas and affirming Israel’s right to exist, labeling such measures as overly broad attempts to stifle speech. In late October 2023, Massie broke with his party by voting against a $14.3 billion aid package to Israel. During an appearance on the podcast of controversial political commentator Tucker Carlson, Massie criticized the American Israel Public Affairs Committee (AIPAC) — the foremost pro-Israel lobbying group in the US — accusing the organization of employing “AIPAC babysitters” to steer congressional votes.
