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 be forced to shutter in the U.S. as soon as Sunday.

The Supreme Court has unanimously upheld the federal law banning TikTok beginning Sunday unless it’s sold by its China-based parent company.

The U.S. 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 the short-video app by Sunday, as the justices in a 9-0 decision declined to rescue a platform used by about half of all Americans.
