Washington — The Supreme Court on Friday upheld a new law that would lead to a ban of the social media platform TikTok, clearing the way for the widely popular app to shutter in the U.S. as soon as Sunday.

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 upheld on Friday a law banning TikTok in the United States on national security grounds if its Chinese parent company ByteDance does not sell it, putting the popular short-video app on track to go dark in just two days.
