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.

While alternatives have emerged recently, this ruling should be and is the final say on whether the TikTok ban will actually go into effect.
