TikTok said it will have to “go dark” this weekend unless the outgoing Biden administration assures the company it won’t enforce a shutdown of the popular app after the Supreme Court on Friday unanimously upheld the federal law banning the app unless it’s sold by its China-based parent company.

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.
