The Obama administration is considering taking a count of DHS contract workers, following a similar unsuccessful attempt six years ago. Industry leaders resisted the previous contractor census, arguing that employment numbers were privileged information. "The attitude was, 'You're not buying people, you're buying a service,'" said a DHS undersecretary testifying on Tuesday before the Senate Homeland Security Committee. Sen. Claire McCaskill, D-Mo., vowed to push for greater transparency. "People may have misinterpreted my interest in this area as being against contractors and privatization," she said. "I'm not. What I'm against is doing it in a way in which we never know whether we get bang for our buck."
