TikTok warned it will go dark in the United States unless President Joe Biden's administration provides assurances to companies like Apple and Google that it will not face enforcement actions when a ban takes effect.

The Supreme Court upheld a law banning TikTok in the US over national security concerns unless its Chinese parent ByteDance sells it. Without immediate assurances from the Biden administration, the app will go dark on January 19.

Trump suggests he will extend the ban deadline by 90 days as Biden’s administration signals it won’t try to stop TikTok’s threatened shutdown on Sunday.
