The Supreme Court will hear arguments Friday on a law that could ban new downloads or updates of TikTok in the U.S.

A US law requires TikTok's Chinese owner, ByteDance, to sell the social media company to an American firm or face a ban.

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