“Without me, Trump would have lost the election, Dems would control the House and the Republicans would be 51-49 in the Senate,” Musk tweeted in response to Trump criticizing Musk for the first time Thursday over Musk’s attacks on his policy bill.

“Such ingratitude,” Musk added.

Trump insinuated in an Oval Office press conference Thursday the Tesla CEO opposes the legislation because he is “upset” the electric vehicle incentive was removed, adding that he’s not sure he’ll remain friends with Musk, marking Trump’s first comments on the feud since Musk began publicly attacking the legislation earlier this week.

Musk didn’t reject the accusation about the EV tax credits in a tweet responding to Trump, writing it was “very unfair!!” that oil and gas subsidies were left in the bill, adding in a subsequent tweet “this bill was never shown to me even once and was passed in the dead of night so fast that almost no one in Congress could even read it!”

Trump also suggested Musk is suffering from what he refers to as “Trump derangement syndrome,” which he describes as people turning on the president after they leave his administration.

Earlier Thursday, Musk reposted a 2013 tweet from Trump that said he was in disbelief and “embarrassed” Republicans were extending the debt ceiling, captioning the repost “wise words,” after Trump said Wednesday the debt limit should be “entirely scrapped” as a provision of his “One Big Beautiful Bill Act,” which would raise the debt ceiling ahead of its expected expiration date in August.
