Billionaire Elon Musk said on Wednesday he regrets some of the posts he made last week about US President Donald Trump as they went “too far.”

Trump and Musk began exchanging insults last week on social media, with the Tesla and SpaceX CEO describing the president’s sweeping tax and spending bill as a “disgusting abomination.”

Trump said on Saturday their relationship was over, but has since said that he would not have a problem if Musk called and wished him well.

“I regret some of my posts about President Donald Trump last week. They went too far,” Musk wrote in a post on his social media platform X.

He did not say which specific posts he was talking about.

Their blistering break-up — largely carried out on social media before a riveted public on Thursday last week — was ignited by Musk’s harsh criticism of Trump’s so-called “big, beautiful” spending bill, which is currently before Congress.

Some lawmakers who were against the bill had called on Musk — one of the Republican Party’s biggest financial backers in last year’s presidential election — to fund primary challenges against Republicans who voted for the legislation.

Musk’s expression of regret came just days after Trump threatened the tech billionaire with “serious consequences” if he sought to punish Republicans who vote for the controversial spending bill, while also branding Musk “disrespectful.”

Tesla shares in Frankfurt were up 2.44 percent after Musk’s post expressing regret.

Since the dispute began, Musk has deleted some social media posts critical of Trump, including one signaling support for impeaching the president.

Sources close to Musk had said his anger has started to subside, and that they believe he may want to repair his relationship with Trump.
