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.

A majority of the Supreme Court appeared likely to uphold a controversial ban on TikTok over concerns about its ties to China, with justices lobbing pointed questions at lawyers for the social media app and a group of its content creators.

The Supreme Court heard TikTok's case to toss out a ban just nine days before it will take effect. The Biden administration defended the measure on national security grounds.
