A leading civil liberties group is suing Homeland Security, claiming the agency is keeping the details of its airport face recognition program secret, which it says raises “profound civil liberties concerns.”

The American Civil Liberties Union filed the lawsuit in a New York federal court on Thursday, demanding that the agency turns over records to understand the scope of its airport face recognition system. The group wants to know who Homeland Security works with — including private companies and airlines — as well as internal policies and guidance on how the system is used.
