A federal appeals court panel on Friday upheld a law that could lead to a ban on TikTok in a few short months, handing a resounding defeat to the popular social media platform as it fights for is survival in the U.S.

The U.S. Court of Appeals for the District of Columbia Circuit ruled that the law, which requires TikTok to break ties with its China-based parent company ByteDance or be banned by mid-January, is constitutional, rebuffing TikTok’s challenge that the statute ran afoul of the First Amendment and unfairly targeted the platform.
