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.

President Biden, on the eve of leaving office, is punting the issue of the U.S. government’s enforcement of the law requiring TikTok’s Chinese parent to sell its stake in the app or face a nationwide ban to President-elect Donald Trump.
