It has captured the attention of teenagers, celebrities and global brands.And now U.S. lawmakers and regulators are interested in TikTok, the video app downloaded by 1 billion people.According to Reuters, the U.S. government is launching a national security review into the Chinese company ByteDance’s 2017 acquisition of U.S. app Musical.ly.
