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.

White House Press Secretary Karine Jean-Pierre called TikTok’s threat to “go dark” tomorrow a “stunt,” and said there is no reason that TikTok or any other companies should take any actions under the ban before the Trump administration is sworn in Monday morning,

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