The U.S. Supreme Court said Wednesday that it will hear TikTok's appeal to avert a government-imposed sale or shutdown next month, taking up the video-sharing app's First Amendment challenge to the federal Protecting Americans from Foreign Adversary Controlled Applications Act.

The court's announcement comes just two days after TikTok and its China-affiliated holding company ByteDance requested an emergency injunction barring the government from enforcing the law. The act, signed by President Joe Biden in April, requires TikTok to be either divested or shut down in the United States.
