TikTok and its Chinese parent company ByteDance are suing the U.S. federal government over a law that would ban the popular video-sharing app unless it's sold to another company. The lawsuit filed on Tuesday may be setting up what could be a protracted legal fight over its future in the United States. The popular social video company alleged the law, which President Joe Biden signed as part of a larger $95 billion foreign aid package, is so "obviously unconstitutional" that the sponsors of The Protecting Americans From Foreign Adversary Controlled Applications Act are trying to portray the law not as a ban, but as a regulation of TikTok's ownership.

A bipartisan group of senators wants restrictions on the use of facial recognition technology by the Transportation Security Administration. The lawmakers say they're concerned about travelers' privacy and civil liberties. In a letter Thursday, 14 lawmakers are calling on Senate leaders to use the upcoming reauthorization of the Federal Aviation Administration to limit use of the technology so Congress can put in place some oversight. TSA has been rolling out the technology at select airports in a pilot project. The agency says the system improves accuracy of identity verification without slowing passenger speeds at checkpoints. Passengers can opt out. The TSA says photos and IDs are deleted after the passenger goes through the checkpoint.

Apple says a Justice Department antitrust lawsuit accusing it of engineering an illegal monopoly in smartphones in the U.S. is "wrong on the facts and the law." The lawsuit was filed Thursday in federal court in New Jersey. The suit alleges Apple uses its control over the iPhone to engage in an "illegal course of conduct." The lawsuit is the latest example of the Justice Department's approach to aggressive enforcement of federal antitrust law that officials say is aimed at ensuring a fair and competitive market. Apple has defended the digital fortress known as its walled garden as a feature prized by consumers who want to protect their personal information.
