U.S. Senators voice concerns about TikTok for national security

Senate Intel leaders Mark Warner (D-VA) and Marco Rubio (R-FL) spoke with CBS’s ‘Face the Nation’ host Margaret Brennan about TikTok, saying the app is “a national security issue.” They argued the Chinese government’s access to American data is “what we need to confront.” “It has an algorithm, a recommender engine, which is one of the best in the world,” Rubio says.
