TikTok said it will have to “go dark” this weekend unless the outgoing Biden administration assures the company it won’t enforce a shutdown of the popular app after the Supreme Court on Friday unanimously upheld the federal law banning the app unless it’s sold by its China-based parent company.

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,
