The Supreme Court will hear TikTok's challenge to the Protecting Americans from Foreign Adversary Controlled Applications Act on January 10, 2025. The company contests a law mandating divestiture from its Chinese parent, ByteDance, by January 19 to avoid a nationwide ban. TikTok argues this ban infringes on free speech for its 170 million users, while the Justice Department cites national security risks. The decision could determine the app's future in the U.S. amid a contentious debate over data security and free expression.
