Former President Donald Trump has discussed a potential White House advisory role for entrepreneur Elon Musk if he is reelected in November, according to a new report in The Wall Street Journal.

The publication, citing people familiar with their discussions, reported that Trump and Musk have held several phone conversations since a meeting in March at the Palm Beach, Florida, home of billionaire Nelson Peltz. Trump hasnt made any official offer, but a role could give Musk input on policies such as border security and the economy, the Journal said.

Musk has already pledged that he will not donate any money to either major candidate for president, not Trump nor Joe Biden . But the Journal added that the owner of X, formerly Twitter, plans to use his social media power to persuade others in elite business and technology circles not to support Biden.

The report is an about-face for the pair, who have had a testy relationship in the past. Musk served on a business council during Trumps presidency but left after Trump decided to withdraw the U.S. from the landmark Paris climate agreement. Trump called the Tesla CEO a bullshit artist at the time.
