TikTok said it would “go dark” on Sunday unless President Joe Biden’s administration offered assurance that it would not enforce a ban upheld Friday by the Supreme Court for the app’s U.S. operations to be sold or booted over “national security concerns.

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.

The Chinese-owned company said it would cut off its services unless the U.S. assures Apple, Google and other companies that they would not be punished for hosting and distributing TikTok.
