Elon Musk steps up attacks on Trump once again - as the president fights back

Elon Musk has stepped up his attacks on Donald Trump's sweeping tax and spending bill - weeks after a spectacular fallout between the world's richest man and the US president.

Following weeks of relative silence after clashing with Mr Trump over his "big beautiful bill", the billionaire vowed to unseat politicians who support it.

In a post on X, Musk said those who had campaigned on cutting spending but then backed the bill "should hang their heads in shame".

He added: "And they will lose their primary next year if it is the last thing I do on this Earth."

Musk also threatened to put their faces on a poster which said "liar" and "voted to increase America's debt" by $5trn (£3.6trn).

The posts attracted a swift reply from Mr Trump, who claimed the billionaire "may get more subsidy than any human being in history" for his electric car business.

"Without subsidies, Elon would probably have to close up shop and head back home to South Africa," he wrote on Truth Social.

"No more Rocket launches, Satellites, or Electric Car Production, and our Country would save a FORTUNE. Perhaps we should have DOGE take a good, hard, look at this? BIG MONEY TO BE SAVED!!!"

Musk spent at least $250m (£182m) supporting Mr Trump in his presidential campaign and then led the newly formed Department of Government Efficiency (DOGE), which sacked about 120,000 federal employees.

He has argued the legislation would greatly increase the US national debt and wipe out the savings he claimed he achieved through DOGE.

As the Senate discussed the package, Musk called it "utterly insane and destructive".

The Tesla and SpaceX CEO said the bill's massive spending indicated "we live in a one-party country - the PORKY PIG PARTY!!"

"Time for a new political party that actually cares about the people," he wrote.

Musk previously said some of his social media posts during his dramatic fallout with Mr Trump "went too far".

He had shared a series of posts on X, including one that described Mr Trump's tax and spending bill as a "disgusting abomination".

He also claimed, in a since-deleted post, that the president appeared in files relating to the disgraced paedophile financier Jeffrey Epstein.

But Musk later wrote: "I regret some of my posts about President @realDonaldTrump last week. They went too far."

In response, the president told the New York Post: "I thought it was very nice that he did that."
