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.

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 Supreme Court on Friday heard arguments in TikTok’s emergency appeal seeking to block a federal law from going into effect that would ban the popular video app unless Chinese parent ByteDance sells its stake.
