The Supreme Court's nine justices heard arguments on Friday in a challenge by TikTok and its Chinese parent company ByteDance to a law that would force a sale or ban the widely used short-video app by Jan.

The court heard oral arguments on TikTok’s bid to block a law that would lead to its ban in the U.S. starting Jan. 19 if it isn’t sold by its Chinese owner.

The Supreme Court on Friday seemed likely to uphold a law that would ban TikTok in the United States beginning Jan. 19 unless the popular social media program is sold by its China-based parent company.
