"This technology poses significant threats to our privacy and civil liberties, and Congress should prohibit TSA鈥檚 development and deployment of facial recognition tools until rigorous congressional oversight occurs," the senators wrote.

The effort, led by , D-Ore., , R-La., and , R-Kan., "would halt facial recognition technology at security checkpoints, which has proven to improve security effectiveness, efficiency, and the passenger experience,鈥� TSA said in a statement.

The technology is currently in use at 84 airports around the country and is planned to expand in the coming years to the roughly 430 covered by TSA.

is one of the last must-pass bills of this Congress. The agency regulates airlines and aircraft manufacturers and manages the nation鈥檚 airspace.

TSA, which is part of the Homeland Security Department, has been rolling out the facial recognition technology at select airports in a pilot project. Travelers put their driver鈥檚 license into a slot that reads the card or they place their passport photo against a card reader. Then they look at a camera on a screen about the size of an iPad that captures their image and compares it to their ID. The technology is checking to make sure that travelers at the airport match the ID they present and that the identification is real. A TSA officer signs off on the screening.

The agency says the system improves accuracy of identity verification without slowing passenger speeds at checkpoints. The technology is not being used as a surveillance tool to compile a database or monitor people in and around the checkpoints, according to the TSA. It says the photos and IDs are deleted after the passenger goes through the checkpoint.

Passengers can opt out, although David Pekoske, the TSA administrator, that eventually biometrics would be required because they are more effective and efficient. He gave no timeline.

Critics have raised questions about how the data is collected, who has access to it, and what happens if there is a hack. Privacy advocates are concerned about possible bias in the algorithms and say it is not clear enough to passengers that they do not have to submit to facial recognition.

鈥淚t is clear that we are at a critical juncture," the senators wrote. 鈥淭he scope of the government鈥檚 use of facial recognition on Americans will expand exponentially under TSA鈥檚 plans with little to no public discourse or congressional oversight.鈥�
