The U.S. Supreme Court’s decision could come Friday in the case about whether TikTok must shut down in a few days under a federal law that seeks to force its sale by the Chinese company that owns the social media platform.

The Supreme Court on Friday was divided over the constitutionality of a federal law that would require social-media giant TikTok to shut down in the United States unless its Chinese parent company can sell it by Jan.

A pending law would pressure China-based ByteDance to sell TikTok for the social media platform to be hosted by U.S. app stores.
