Elon Musk just went nuclear on the Republican Party.
In a blistering post on his X platform Monday, the billionaire CEO torched GOP lawmakers for backing what Donald Trump has called his “big, beautiful bill”—a sweeping package of tax cuts that also slashes over $1 trillion from social programs.
“Every member of Congress who campaigned on reducing government spending and then immediately voted for the biggest debt increase in history should hang their head in shame!” Musk wrote. “And they will lose their primary next year if it is the last thing I do on this Earth.” should hang their head in shame!” he posted on X.
“And they will lose their primary next year if it is the last thing I do on this Earth,” he added.
This fiery warning came the same day Musk met with Indian Prime Minister Narendra Modi in Washington, D.C., but the headlines were all about his warpath against Republicans.
The bill has already sparked outrage from Democrats, who point to deep cuts in Medicaid, food assistance, and clean energy programs—all while handing massive tax breaks to the ultra-rich.
But Musk, once a high-profile ally of Trump, is attacking it from the opposite direction. His main complaint? It blows up the federal deficit without doing enough to actually reduce government waste.
He’s now promising to fund primary challengers to take out Republicans who go along with it.
The clash marks a stunning turn in Musk’s political trajectory. Once aligned with Trump’s economic agenda, Musk is now openly accusing the GOP of hypocrisy and financial recklessness.
Some conservatives are hardly surprised.
“Disillusionment is a natural stage of a person who did real things in life before finding politics,” wrote far-right commentator Mike Cernovich. “Republicans never cared about spending. Paul Ryan gave Obama everything he wanted.”
Others questioned whether Musk could actually deliver on his threat. Finding candidates who match his views on spending and energy policy—without alienating Trump’s base—won’t be easy.
“Musk can find people to run who agree with him on spending, he can find people to run who agree with him on energy,” noted Washington Post opinion editor Benjy Sarlin. “It’s gonna be real hard to find both and there’s not a lot of opportune targets for either.”
