It’s not over for TikTok. Or is it? Today on “Post Reports,” why the app went dark in the United States, how it came back and who controls its fate. Read more:Last week, the Supreme Court upheld a federal law banning TikTok in the United States unless its Chinese parent company, ByteDance, sold to an American buyer. On Sunday, the popular video-sharing app went dark, only to come back later that night. And on Monday, Trump signed an executive order to halt the ban. Today on “Post Reports,” tech reporter Drew Harwell digs into the national security arguments that swayed the court’s decision, why Trump’s opinion on the app has flip-flopped and why users of the platform might still feel like they’re in purgatory. And, we hear from Dave Jorgenson, the face of The Washington Post’s TikTok team, about how TikTok users are feeling amid the turmoil. Today’s show was produced by Rennie Svirnovskiy and Bishop Sand. It was mixed by Sam Bair and edited by Lucy Perkins and Monica Campbell.
