ELON Musk has slammed Donald Trump’s “big, beautiful” tax and spending bill, calling it a “disgusting abomination” on X.

The tech mogul’s recent criticism of a key initiative by the US president follows shortly after his resignation as the leader of the Department of Government Efficiency (DOGE).

The legislation, approved in May, features massive tax cuts running into trillions and a boost in defense budget, while also permitting the US to increase its borrowing.

Mr Musk, who campaigned to reduce the national debt, used his X platform to fume: “I’m sorry, but I just can’t stand it anymore.

“This massive, outrageous, pork-filled Congressional spending bill is a disgusting abomination.

“Shame on those who voted for it: you know you did wrong. You know it.

“It will massively increase the already gigantic budget deficit to $2.5 trillion and burden American citizens with crushingly unsustainable debt.

“Congress is making America bankrupt.”

Musk had previously called the bill “disappointing”, claiming it undermined the cost-cutting work of the DOGE.

Mike Johnson, the Speaker of the US House of Representatives, responded quickly, stating: “With all due respect, Elon has misunderstood the one substantial, admirable bill.”

It comes days after Mr Trump sent what he has called the “big, beautiful bill” to Congress, where it is awaiting approval from the Senate.

If passed, it would see America’s national debt ceiling raised by $5 trillion (£3.7trillion).
