The law—which prohibits U.S. app stores from hosting TikTok unless Chinese parent company ByteDance divests from it—is scheduled to take effect one day before Trump’s Jan. 2

Donald Trump has claimed he would “save TikTok in America, ” a far cry from the days of 2020 when he sought to ban the social media platform via an executive order.

The court heard oral arguments on TikTok’s bid to block a law that would lead to its ban in the U.S. starting Jan. 19 if it isn’t sold by its Chinese owner.
