A new official account for the White House is on the social media platform TikTok. The administration has been delaying a shutdown of the service as it seeks to work up a deal for American ownership. The White House has officially joined TikTok, even as the administration is trying to help determine the future of the platform in the US.

The White House launched a TikTok account on Tuesday amid uncertainty about the app’s future, as another deadline approaches for its parent company, Bytedance, to sell to a US buyer or be banned in the United States.
