Donald Trump had asked the Supreme Court to delay TikTok’s ban-or-sale law to give him an opportunity to act once he returns to the White House.

The Supreme Court on Friday unanimously upheld the federal law banning TikTok beginning Sunday unless it's sold by its China-based parent company, holding that the risk to national security posed by its ties to China overcomes concerns about limiting speech by the app or its 170 million users in the United States.
