TikTok docket

TikTok is taking Trump to court, and in its new legal filing the social video app disclosed new details about just how popular it is, with more than 100 million monthly active users in the U.S.

The company, which is owned by Chinese-based ByteDance, has signaled for weeks that it would appeal to federal courts after President Donald Trump signed executive orders to shut down the app in the U.S. On Monday, TikTok finally sued the Trump administration.

The New York Times reports that it will be tough for TikTok to challenge U.S. authorities that have wide latitude to declare national security threats. “Jason M. Waite, a partner at the law firm Alston & Bird, said courts would probably be reluctant to challenge the president on national security grounds. But if a court does decide to rule against Mr. Trump, that could end up curtailing the powers of the presidency,” The Times writes.

In its court papers, TikTok said it is seeing explosive growth with more than 100 million monthly active U.S. users. It had closer to 40 million monthly U.S. users in October, when Ad Age reported on leaked documents about its advertising program.

TikTok also said it has about 50 million daily active users in the U.S., according to CNBC.
