TikTok is an online platform that allows individuals anywhere in the world to create, share, and view videos on subjects of their choice. The owner of 21% of the company is a Chinese citizen, and beginning in 2020, the federal government began to express concerns that data gathered from its American users, currently numbering 170 million annually, might be given to the Chinese government, which may also be using TikTok to disseminate Chinese propaganda to unsuspecting American citizens. Congress's answer, which President Joe Biden signed into law on April 23, 2024, is the Protecting Americans from Foreign Adversary Controlled Applications Act. Its real name should have been the Putting TikTok Out of Business Act, because that is what it is intended to do.

The act allowed TikTok to challenge it in the U.S. Court of Appeals for the District of Columbia Circuit, which it immediately did. TikTok filed its brief on June 18, and the government's response is due July 26, with oral argument set for Sept. 16. The reason for the haste is that unless TikTok can comply with the statutory option to sell the business to someone else by Jan. 19—a practical impossibility—TikTok will have to stop operating, with its shareholders and one billion users worldwide left with nothing.
