The Supreme Court today agreed to hear TikTok‘s challenge to a law that could lead to a ban of the social media platform’s presence in the U.S.

The high court set Jan. 10 for oral arguments, just nine days before TikTok has said it would face being restricted.

Congress overwhelming passed a law last year to force TikTok’s Chinese parent, ByteDance, to sell its U.S. operations or face a ban on app stores.

TikTok has challenged the law on First Amendment grounds. After an appeals court rejected the challenge, TikTok asked the Supreme Court for an emergency ruling.

More to come.
