Former President Donald Trump announced Saturday night that he has joined TikTok, even as many in his party criticize the popular app and call for its China-based parent company to divest. Trump’s first post on the platform was a 13-second video, which appeared to be filmed at the UFC event in New Jersey he attended Saturday. In the first shot, Trump is joined by UFC President Dana White, who announces, “The president is now on TikTok.” “It’s my honor,” Trump responds as the TikTok cuts to a montage of the former president greeting fans at the arena.
