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.

After the Supreme Court heard oral arguments over a law that could ban TikTok, it looks like one of its last possible lifelines is unlikely to save it from the impending ouster.
