“It is obvious with the insane spending of this bill, which increases the debt ceiling by a record FIVE TRILLION DOLLARS that we live in a one-party country — the PORKY PIG PARTY!!” Musk said in a post on X. “Time for a new political party that actually cares about the people.”

“How can you call yourself the Freedom Caucus if you vote for a DEBT SLAVERY bill with the biggest debt ceiling increase in history?” he added, specifically tagging Reps. Andy Harris (R-MD) and Chip Roy (R-TX).

Musk threatened to turn his threats into action in a follow-up post.

“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! And they will lose their primary next year if it is the last thing I do on this Earth,” he vowed.

Musk said his new party would be founded immediately after the One Big Beautiful Bill Act passes.

“If this insane spending bill passes, the America Party will be formed the next day. Our country needs an alternative to the Democrat-Republican uniparty so that the people actually have a VOICE,” he said.

Musk criticized the Senate’s version of the bill as “utterly insane and destructive” on Sunday, saying it would “destroy millions of jobs in America and cause immense strategic harm to our country!”

Sens. Rand Paul (R-KY) and Thom Tillis (R-NC) showed support for Musk’s criticisms of the bill, with Musk reposting Tillis’s praise on Monday.

Musk’s new threats are likely to draw the ire of Trump himself after their explosive feud, which ignited earlier this month, had begun to cool down. The president gave a charitable assessment of Musk in a Friday interview with Fox Business host Maria Bartiromo, which was aired on Sunday.

“He got a little bit upset, and you know that wasn’t appropriate,” Trump said of Musk’s blowup earlier this month, adding that he has “not spoken to him much” since.

Trump again pinned the real reason for the public argument on the rescission of electric vehicle subsidies, though he sprinkled praise for Musk throughout.

MUSK BLASTS ‘INSANE AND DESTRUCTIVE’ SENATE VERSION OF TRUMP TAX BILL

“I don’t want everybody to have to have an electric car. You know, I campaigned on, you have a choice if you want a gasoline power, if you want a hybrid, if you want — I love the electric, I love his cars. I think he’s fantastic, but not everybody should have that.”

The founding of a new party would likely make his rift with Trump permanent. Musk had previously begun scaling back some of his rhetoric, saying he regretted “some” of what he said on June 5 and that he had gone “too far.”
