Joe Lieberman’s Senate Committee on Homeland Security and Governmental Affairs will hold a hearing today at 3:15pm EST to discuss “Closing the Gaps In Air Cargo Security” with TSA Director John Pistole. Lieberman got a head start on the issue, of course. He was on MSNBC yesterday in an interview with Andrea Mitchell, who brought up conversing about full body scanners and security “pat downs.” When asked whether or not he believed that the procedures are invasive, he responded, “I come down on the side of pat downs.”
