The order follows TikTok going dark for about 14 hours after the Supreme Court upheld a law prohibiting the service from operating in the U.S. unless it breaks away from its parent company in China.
The president-elect said he will issue an executive order Monday to delay the ban while he brokers a sale. The app has returned on web and mobile, but is not available in Apple and Google's stores.
The app had more than 170 million monthly users in the U.S. The black-out is the result of a law forcing the service offline unless it sheds its ties to ByteDance, its China-based parent company.
The decision resolves a long-running legal dispute between the Department of Justice and TikTok. But experts say President-elect Donald Trump will now have considerable sway over the platform's future in the U.S.
With TikTok's days in the U.S. likely numbered, many American users are moving to another Chinese social media app: RedNote, a heavily censored platform similar to Instagram. Here's what to know.
Even if the controversial U.S. ban on TikTok does take effect on Jan. 19, the app won't automatically vanish from phones. Here's what would change, plus preparations and potential work-arounds.
Lawyers for TikTok argued that banning the app will violate the free speech of 170 million American users. The Justice Department contended that the app is a national security risk.
President-elect Donald Trump asked the Supreme Court on Friday to pause the potential TikTok ban from going into effect until his administration can pursue a "political resolution" to the issue.
