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 said it may announce opinions on Friday, a last-minute addition that comes just two days before a law that would ban TikTok is set to go into effect.

The app’s availability in the U.S. has been thrown into jeopardy over data privacy and national security concerns.
