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.

The federal ban on TikTok is set to take effect Sunday unless the Supreme Court steps in to stop it, and while reports Wednesday suggest President-elect Donald Trump is mulling an executive order that would quickly reinstate the app, he may have limited options should the law be upheld—and his attempts to stop it could be challenged in court.

President Joe Biden won't enforce a ban on the social media app TikTok that is set to take effect a day before he leaves office on Monday, a U.S. official said Thursday, leaving its fate in the hands of President-elect Donald Trump.
