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

The tech tycoon’s public attack on one of the US president’s signature policies comes just days after he stepped down as head of the Department of Government Efficiency (DOGE).

The bill, passed in May, includes multi-trillion dollar tax breaks and increased defence spending while also allowing the US government to borrow more money.

The tech billionaire said on X that those who voted to pass the bill are “wrong”.

Mike Johnson, speaker of the US House of Representatives, soon after said: “With all due respect, Elon is terribly wrong about the one big beautiful bill.”

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