Justice Department Investigating Surveillance by TikTok's Owner

The Justice Department is investigating the surveillance of American citizens, including several journalists who cover the tech industry, by the Chinese company that owns TikTok, according to three people familiar with the matter. The investigation, which began late last year, appears to be tied to the admission in December by the company, ByteDance, that its employees had inappropriately obtained the data of American TikTok users, including that of two reporters and a few of their associates.
