TikTok has filed an emergency petition with the US Supreme Court to challenge a federal law that could force the platform to shut down in January. The law requires TikTok to sever ties with its Chinese parent company or face a nationwide ban. TikTok argues that the law violates First Amendment rights and would cause irreparable harm to its business. The Supreme Court's response will determine the fate of the popular social media platform, which has 170 million US users.
