Former President Donald Trump and Tesla CEO and X owner Elon Musk hosted a friendly conversation Monday on X after their interview was delayed by more than 40 minutes due to technical difficulties.

The delay of the high-profile interview was the Trump campaign’s latest stumble as it looks to regain momentum following the Democratic Party coalescing around Vice President Kamala Harris. It also marked the second time Musk suffered a setback while trying to launch a highly attended X Space with a presidential candidate.

The discussion between the former president and the richest man in the world, who has endorsed Trump, marked Trump’s return to X after his account had remained dormant for nearly a year.

The last time Trump had posted on the social media website was when he posted his mugshot from being processed at an Atlanta jail in the Georgia election subversion case in August of last year. Trump had gained around 900,000 new followers as of Monday night since he started posting again on the platform.
