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.

The app says it will shut down Sunday unless the sitting president can assure tech companies that he won’t enforce the law.

TikTok on Friday said that it would turn off more than 170 million Americans’ access to the super popular video app on Sunday, unless President Joe Biden’s administration acts urgently to assure the company it will not be punished for violating the terms of its looming ban.
