The US Supreme Court will hear arguments on January 10 regarding the constitutionality of a federal law that could ban TikTok unless its Chinese parent company, ByteDance, sells it. The law, enacted in April, has a deadline of January 19 for TikTok's sale. The case raises issues of free speech versus national security, with arguments from TikTok's lawyers and content creators. The Biden administration's Justice Department will defend the law, while the incoming Trump administration may have a different stance.
