The Supreme Court signaled in oral arguments Friday that it may uphold the federal ban on TikTok, potentially leaving it up to President-elect Donald Trump to try and keep the app legal once he takes office — but the president-elect has limited options if the law is upheld, and any attempts to stop it could be challenged in court.

WASHINGTON (AP) — The law that could ban TikTok is coming before the Supreme Court on Friday, with the justices largely holding the app’s fate in their hands. The popular social media platform says the law violates the First Amendment and should be struck down.
