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.

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.

White House Press Secretary Karine Jean-Pierre called TikTok’s threat to “go dark” on Sunday, January 19th, a “stunt,” and that there is no reason for TikTok to shut itself down before President-elect Donald Trump is sworn in on the 20th.
