President-elect Donald Trump on Friday intervened in the Supreme Court case that ultimately could decide whether a federal ban on TikTok occurs.

Trump has reversed his position on the popular app, having tried to ban it during his first term in office over national security concerns. He joined the TikTok during his 2024 presidential campaign and his team used it to connect with younger voters, especially male voters, by pushing content that was often macho and aimed at going viral.
