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.

In response to concerns that China can use the platform to spy on Americans and spread propaganda, Congress last year passed a law requiring TikTok’s parent company to sell it to a non-Chinese owner. TikTok and the parent company, ByteDance, then sued to block the law. This morning, the Supreme Court will hear arguments in the case.

The Chinese-owned app is battling for survival as a deadline looms over its fate.
