Trump was barred from the platform in January 2021 in the final days of his presidency amid unrest following the Jan. 6 attack on the U.S. Capitol.

Tech billionaire Elon Musk said Tuesday that he would allow former President Donald Trump back on Twitter after Musk completes his plan to buy the company, giving the most concrete example yet of how his vision of social media would play out in reality.

Musk said at an event sponsored by The Financial Times that it was “morally bad” and “foolish in the extreme” for Twitter to “permanently suspend” Trump in January 2021 after Trump’s supporters violently stormed the U.S. Capitol, according to a video of the event posted online.

“I do think that it was not correct to ban Donald Trump,” Musk, the CEO of Tesla, said at the newspaper’s Future of the Car event by remote video.

“I think that was a mistake, because it alienated a large part of the country and did not ultimately result in Donald Trump not having a voice,” he said, citing Trump’s newly launched tech platform, Truth Social.

“I would reverse the permanent ban,” Musk said.
