The Supreme Court is set to hear a case involving TikTok's challenge to a US law that may ban the app, citing First Amendment rights. The government argues the law is about regulating foreign entities collecting data on Americans, not free speech. TikTok's parent company, ByteDance, is required by Congress to sell the app, which they are contesting. The court has expedited the case, indicating a swift decision is likely. TikTok users have also filed a lawsuit, concerned about the potential impact on their accounts. Former President Trump, who previously sought to ban TikTok, could influence the outcome if he returns to office by instructing the Attorney General not to enforce the ban or by seeking legislative changes.
