TikTok is facing a barrage of opposition from US officials amid ongoing security concerns over the ByteDance-owned app. Last week, South Dakota Governor Kristi Noem signed an executive order prohibiting state employees and contractors from installing or using TikTok on state devices, a move which was followed by Indiana suing the popular Chinese-owned video-sharing platform on Dec.7 over allegations that it deceived users about content and data security, and allowed children access to mature content. Meanwhile, the Governors of Texas, Maryland, and South Carolina all banned the use of TikTok on government phones and computers this week. The Wall Street Journal on Tuesday cited a source familiar with the matter as saying that these actions could delay a national security deal that the Biden administration is expected to reach with TikTok by the end of the year.
