Elon Musk

Last month, he was a no-show for a court ordered appearance at the US Securities and Exchange Commission (SEC) office in Los Angeles.

However, Mr Musk fell unusually quiet on X not posting for several hours on Thursday morning, and on Friday wrote a post indicating he had visited Los Angeles.

The SEC is investigating whether Mr Musk waited too long to disclose he was building up a stake in Twitter before his 2022 takeover - a delay he has previously described as a mistake.

It certainly wasn't love at first sight. In fact, not so long ago they didn't like each other very much.

"I don't hate the man," Elon Musk tweeted in July 2022, "but it's time for Trump to hang up his hat & sail into the sunset."

The Tesla and Space X founder's comment was prompted by a profane Donald Trump insult - put simply, calling Mr Musk a liar. Trump accused Mr Musk of lying to him about who he voted for in the last presidential election.

"Elon is not going to buy Twitter," Trump crowed to a rally crowd in Alaska.

Former President Donald Trump is holding a rally to announce his economic proposals and hit out at the "hardships created by the Harris-Biden Administration" in North Carolina on Wednesday, as he faces increased scrutiny from union workers.

Trump has come under fire from union members for voicing support for firing workers who strike, which he brought up during a social media conversation with Tesla CEO Elon Musk earlier this week.

The United Automobile Workers (UAW) union has since filed charges with federal labour regulators on accusations of intimidation.
