The Biden administration will not force TikTok to shut down in the U.S. on the eve of the presidential transition, signaling that enforcement of a law necessitating such action will fall to the incoming administration. The law targets app stores and internet services that work with TikTok, owned by China's ByteDance, and imposes severe fines. An extension to delay enforcement was blocked in the Senate due to national security concerns. Although President-elect Donald Trump, favoring TikTok for his campaign, is considering executive actions to keep the app available, a Supreme Court ruling could uphold the law, underscoring concerns over Chinese intelligence threats.
