The Supreme Court is considering a possible TikTok ban. Here's what to know about the case

The law that could ban TikTok is coming before the Supreme Court. The justices largely hold the app’s fate in their hands as they hear the case Friday. The popular social media platform says the law violates the First Amendment and should be struck down. The U.S. government argues that the app having a China-based parent company means it's a potential national security threat. Three appeals court judges have sided with the government and upheld the law, which bans TikTok unless it’s sold. The law is set to take effect Jan. 19, right before a new term begins for President-elect Donald Trump. The Republican has asked for the law to be paused to “save TikTok.”
