The U.S. Senate has passed a bill that would ban TikTok from operating in the United States unless it is sold off by its Chinese owner, ByteDance. The move comes amid concerns that the app poses a national security risk by collecting data on American users. ByteDance has denied these allegations. If the ban goes into effect, TikTok would not disappear from users’ phones but updates and new downloads would not be available from U.S. app stores. The bill is expected to face legal challenges.
