TikTok has restored service in the U.S. less than 24 hours after its nationwide shutdown. On Sunday, Jan. 19, TikTok announced on X, via an official statement shared to its policy account, that it is "in the process of restoring service" to Americans after going dark the night prior .

A U.S. ban of TikTok began to take effect on Sunday, capping a high-stakes battle that pitted the federal government against one of the nation's most popular social media platforms.

The president-elect Sunday pledged an executive order, hours into his second term, returning access for American users, at least temporarily.

President-elect Donald Trump says he will sign an executive order that would give the China-based parent company of the popular video-sharing platform TikTok more time to find an approved buyer

Trump announced the decision in a post on his Truth Social account on Sunday as millions of TikTok users in the U.S. awoke to discover they could no longer access the TikTok app or platform.

U.S. officials have long feared that the widely popular short-form video app could be used as a vehicle for espionage.

Senators Tom Cotton and Pete Ricketts said "there's no legal basis" for an extension to keep the social media platform online.

In a post on Truth Social, Trump also laid out what he thinks a “qualified divestiture” of TikTok by ByteDance could look like.

The company said in a statement that TikTok was coming back online in the U.S. after President-elect Donald Trump provided assurances to the company’s service providers.

Looming over the Supreme Court's TikTok decision is what could happen after Donald Trump takes office. Trump promised to "save" the popular platform.
