One of the leading congressional critics of China has introduced legislation that would give the president additional power to crack down on TikTok and other apps owned by foreign adversaries.

House Select Committee on the Chinese Communist Party Chairman Mike Gallagher (R-WI) introduced the Protecting Americans from Foreign Adversary Controlled Applications on Tuesday. The bill would make it unlawful for app stores to host social media applications owned by companies connected to “foreign adversaries” such as China, Russia, or Iran, specifically focusing on TikTok and its parent company ByteDance. It would also give the president the power to designate other social media apps as being controlled by foreign adversaries and force divestments.
