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.

Meanwhile, the Justice Department is absolutely loving this. The Supreme Court's decision will allow it to "prevent the Chinese government from weaponizing TikTok to undermine America's national security," says Attorney General Merrick Garland. "Authoritarian regimes should not have unfettered access to millions of Americans' sensitive data."
