The Supreme Court is hearing arguments over a law that could lead to TikTok shutting down in the U.S. in less than two weeks.

The justices will review a law that would effectively shut down TikTok in the United States this month unless the company divests from Chinese ownership.

Justices will hear arguments in two consolidated cases taking aim at the federal law, which requires Chinese-owned ByteDance to divest from TikTok, or else TikTok will be banned from U.S. app stores and from being hosted by American internet service providers.
