A bipartisan group of senators, led by Jeff Merkley, John Kennedy, and Roger Marshall, is advocating for limitations on the Transportation Security Administration's use of facial recognition technology due to concerns about privacy and civil liberties. PBS reports: In a letter on Thursday, the group of 14 lawmakers called on Senate leaders to use the upcoming reauthorization of the Federal Aviation Administration as a vehicle to limit TSA's use of the technology so Congress can put in place some oversight. "This technology poses significant threats to our privacy and civil liberties, and Congress should prohibit TSA's development and deployment of facial recognition tools until rigorous congressional oversight occurs," the senators wrote.

The effort, led by Sens. Jeff Merkley, D-Ore., John Kennedy, R-La., and Roger Marshall, R-Kan., "would halt facial recognition technology at security checkpoints, which has proven to improve security effectiveness, efficiency, and the passenger experience," 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.
