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

TikTok late Friday warned that it will go dark in the United States on Sunday except President Joe Biden’s administration provides assurances to companies like Apple and Google that they will not face enforcement actions when a ban takes effect.

Trump is seeking to protect TikTok from a new law that gives parent ByteDance until Sunday to sell the app to an American buyer or be banned in the U.S.
