In focus is Donald Trump's state budget, which is on its way to being pushed through Congress.
"Elon Musk knew long before he started supporting my presidential campaign that I strongly opposed (Joe Biden's) support for the electric car market", Trump writes on his platform Truth social.
"It's okay with electric cars, but no one should be forced to buy one", he continues.
Trump's budget proposal, which is now being processed, includes, among other things, significant cuts in support for the electric car market and electric car buyers.
A new party
The President writes that Musk - who founded both the space company SpaceX and the electric car giant Tesla and, according to Bloomberg, is the richest man in the world - has received more subsidies than anyone else and that he would need to "go home to South Africa" without subsidies.
"No more rocket launches, satellites or electric car production and our country would make a fortune", Trump writes, partly in capital letters.
In response to a direct question from journalists outside the White House on Tuesday about whether the President can imagine deporting Musk, who has American citizenship, Trump says he "needs to look at it".
Musk, on the other hand, calls the budget "insane". On the platform X, which he himself owns, Musk writes that he will start a new party, the American Party, if the budget is passed. He has previously been an outspoken opponent of the budget proposal, both due to the cuts in electric car support and because he believes it will increase the US national debt.
Investigated by Doge?
Elon Musk was often seen by Donald Trump's side during the election campaign last autumn and during the first months after the President's inauguration. He was given the task of leading the White House's efficiency organization Doge, which had the task of cutting down on the state's expenses, but left this task in May.
In his post on Truth, Trump suggests that Doge now investigate Musk's business dealings.
