The Supreme Court will hear arguments on Jan. 10 over TikTok’s effort to block a federal ban on the platform if it’s not sold by Jan. 19.

The announcement from the Supreme Court comes days after a lower court rejected TikTok’s request for a temporary pause of the ban. TikTok had argued that a pause would afford the Supreme Court time to weigh the case.

TikTok — which boasts more than 170 million U.S. users — challenged the sale-or-ban law on First Amendment grounds, arguing that a potential ban would limit the free-expression rights of its users.

In a ruling earlier this month, a three-judge panel of the U.S. Court of Appeals for the D.C. Circuit rejected TikTok’s bid to overturn the law.
