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.

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.

The Supreme Court will hear two hours of oral arguments on Jan. 10 in TikTok’s appeal to block enforcement of a federal law that would require TikTok to shut down in the United States unless its parent company can sell off the U.

The president-elect backed TikTok in a Truth Social post Friday as he tries to halt the law from taking effect.

President-elect Donald Trump has urged the Supreme Court to halt the Jan. 19 TikTok ban if parent company ByteDance fails to sell the platform.

The Chinese-owned app is battling for survival as a deadline looms over its fate.

The high court will hear oral arguments in TikTok's case on Friday, just before the ban is slated to go into effect.

President-elect Trump's highly unusual intervention in the Supreme Court's TikTok case reads almost like a guy asking for a favor from an institution that still runs on formality. The big picture: Trump's last-minute effort to give TikTok a stay of execution is one more twist in a case that already scrambles every ideological dividing line.
