Republican presidential nominee Donald Trump is returning to X for a live interview with platform owner Elon Musk Monday, marking one of his most significant returns to the site since he was banned in 2021.

Musk has said their conversation, which starts at 8 p.m. ET, will be “unscripted with no limits on subject matter.”

Musk reinstated Trump’s account on X in 2022, close to two years after Trump was banned from the platform in the aftermath of the Jan. 6 insurrection.

Trump returned to the site only rarely in that time, once to post an image of his mugshot and a fund-raising link after he was indicted for a scheme to overturn the 2020 election results in Georgia.

On Monday he also posted a campaign video to his account.

Trump’s interview with Musk echoes another high-traffic event on the platform, when Florida Gov. Ron DeSantis announced his presidential bid in a group voice channel that was riddled with technical errors due in part to high demand from hundreds of thousands of listeners.

Musk has said X tested its infrastructure ahead of time for Monday’s interview.

Musk endorsed Trump days after the assassination attempt on his life at a campaign event last month.

The Wall Street Journal reported that Musk has pledged to donate $45 million a month to a super PAC that’s supporting Trump’s campaign. However, Musk denied the report and instead said he is donating “at a much lower level” to a super PAC that values “meritocracy & individual freedom.”
