The U.S. Supreme Court will hear arguments this week in a case challenging a law that seeks to ban the popular app TikTok in the United States if it is not sold by its owner, Byte Dance, which is based in China.

Justices will hear arguments in two consolidated cases taking aim at the federal law, which requires Chinese-owned ByteDance to divest from TikTok, or else TikTok will be banned from U.S. app stores and from being hosted by American internet service providers.

Harvard University has hired another law firm to help it navigate a U.S. House investigation into its response to claims of pervasive antisemitism on campus, weeks after mounting criticism helped spur the resignation of Harvard president Claudine Gay.
