Former president Donald Trump has returned to X, the social media site formerly known as Twitter, firing off his first message in more than two years shortly after he surrendered at an Atlanta jail.

He posted a photo of his mugshot and the words “Election interference. Never surrender!” along with a link to his website, which directs to a fundraising page.

It was Mr Trump’s first post since January 8, 2021, when Twitter suspended his account indefinitely, citing fears he would incite additional violence following the deadly storming of the US Capitol building.

His account was reinstated last November shortly after Elon Musk took over the company. But Mr Trump had refrained from tweeting, insisting that he was happier on his own Truth Social site, which he launched during the ban.

Mr Trump, the current front-runner for the Republican presidential nomination, had been saying for months that he planned to return to the platform at the “right time”, according to a person familiar with his comments who was not authorised to disclose private conversations and spoke on condition of anonymity.

Mr Trump’s post came as he was aboard his private plane, flying back from Atlanta to his summer home in New Jersey late on Thursday.

It was not immediately clear whether the post was a one-off, or whether he intends to continue to post regularly on the site. He had posted the same message on Truth Social earlier in the night and continued to promote the site late on Thursday.

“I LOVE TRUTH SOCIAL. IT IS MY HOME!!!” he wrote.

Nonetheless, the message marked a homecoming of sorts for Mr Trump to one of his most important megaphones — one he used to dominate his rivals in the 2016 primary and to command the news cycle for years.

Mr Trump often marvelled at how quickly his missives would travel from his account to cable news stations under the banner “BREAKING NEWS”.

The new post came a day after Mr Trump skipped the first Republican primary debate, choosing instead to tape an interview with former Fox News host Tucker Carlson that was posted on X as counterprogramming at the start of the debate.

The return to X with what was, effectively, a fundraising pitch is also a reflection of just how much money Mr Trump’s campaign has been burning on lawyers as he battles criminal charges in four jurisdictions.

Mr Trump’s political operation entered the second half of the year in a strained financial position with its bank account drained by tens of millions of dollars that were directed toward defending the former president and his allies.

Mr Trump has 86.6 million followers on what is now known as X, dwarfing his rivals in the 2024 race.

But the platform has undergone significant changes since Mr Trump left it, including Mr Musk changing its name.

He returned to Facebook in March, posting, “I’M BACK!” weeks after his personal account there was reactivated.

But he has stuck with Truth Social, the Twitter lookalike he launched after he was suspended from Twitter and Facebook, to post a daily stream of missives, announcements and re-posts.

That has included using the platform to break news of his indictments and planned surrenders as he has faced a mounting list of legal woes.
