President Trump said on Sunday that the Make America Great Again (MAGA) movement should abandon Rep. Thomas Massie (R-Ky.) after his pushback Saturday night against the U.S. strikes on Iran.

In a lengthy post on his Truth Social platform, Trump called Massie “not MAGA” and “a simple minded ‘grandstander’ who thinks it’s good politics for Iran to have the highest level Nuclear weapon.”

“Massie is weak, ineffective, and votes ‘NO’ on virtually everything put before him (Rand Paul, Jr.), no matter how good something may be. He is disrespectful to our great military, and all that they stand for, not even acknowledging their brilliance and bravery in yesterday’s attack, which was a total and complete WIN,” Trump said in his post.

The president name-checked Kentucky Sen. Rand Paul (R) because both he and Massie have opposed the president’s “big, beautiful bill.”

“Massie should drop his fake act and start putting America First, but he doesn’t know how to get there — he doesn’t have a clue! He’ll undoubtedly vote against the Great, Big, Beautiful Bill, even though non-passage means a 68% Tax Increase for everybody, and many things far worse than that. MAGA should drop this pathetic LOSER, Tom Massie, like the plague!” he added.

On Saturday, Trump announced that the U.S. had bombed three Iranian nuclear sites. 

Massie quickly posted on the social platform X that Trump’s bombing of Iranian nuclear sites was unconstitutional.

On Tuesday, Massie introduced a war powers resolution to prohibit U.S. involvement in Iran as its conflict with Israel intensifies, signaling they may force a vote on the matter. Rep. Ro Khanna (D-Calif.) said he would co-sponsor the measure.

The Hill has reached out to Massie’s and Paul’s offices for comment.
