Justices did not issue a ruling in the closely watched case over a potential ban, dialing up intrigue over the app’s fate.

The Supreme Court on Friday was divided over the constitutionality of a federal law that would require social-media giant TikTok to shut down in the United States unless its Chinese parent company can sell it by Jan.

The US Supreme Court heard arguments Friday about whether or not to uphold a law that effectively bans the social media app TikTok. The law was signed last year and calls for the app to be sold by its Chinese parent company ByteDance by Sunday, and the app could be shut down in the US if the law is upheld.
