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 on Friday, with the justices largely holding the app's fate in their hands.

The popular social media platform says the law violates the First Amendment and should be struck down.

TikTok's parent company is based in China , and the U.S. government says that means it is a potential national security threat . Chinese authorities could force it to hand over sensitive data on the huge number of Americans who use it or could influence the spread of information on the platform, they say.

An appeals court has upheld the law, which bans TikTok unless it's sold.

The law is set to take effect Jan. 19, the day before a new term begins for President-elect Donald Trump, who has 14.7 million followers on the platform. The Republican says he wants to 'save TikTok."
