The Supreme Court seemed likely to uphold a new law that could force TikTok to shut down in the U.S., with conservative and liberal justices alike expressing skepticism about the legal challenge.

Congress labeled the app’s Chinese ownership a national security risk and passed a law that would ban the social media platform unless it was sold. TikTok and creators say that violates their free speech rights.

The law that could ban TikTok is coming before the Supreme Court. The justices largely hold the app’s fate in their hands as they hear the case Friday.
