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.

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.

As a ban looms over the social media app and its 170 million users, TikTok said it will be “forced to go dark” on Sunday unless the Biden administration explicitly declares that it will not enforce the ban.
