TikTok’s future in the United States now sits squarely in the hands of the Supreme Court, which will hear oral arguments Friday. At its core, the case features a head-on collision between national security and the First Amendment.

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 U.S. Supreme Court will hear arguments on Friday challenging a law that seeks to ban TikTok in the U.S. on Jan. 19.

The Supreme Court will hear two hours of oral arguments on Jan. 10 in TikTok’s appeal to block enforcement of a federal law that would require TikTok to shut down in the United States unless its parent company can sell off the U.

TikTok‘s general manager of agency business for its U.S. arm left the social media platform. This comes as a pending law would pressure China-based ByteDance to sell TikTok for the social media platform to be hosted by app stores in the United States.

The Supreme Court will make a decision on Friday regarding the potential ban of the popular social media platform TikTok.
