After Congressman Roskam learned of two classified TSA reports claiming security screeners at O'Hare failed to detect 60 percent of bomb materials and explosives hidden in carry-on bags he immediately sought an inspection of O'Hare's security measures with Federal Safety Director, Kathleen Petrowsky. Roskam needed to know what measures were being taken by TSA to rectify the finding of these investigations. It was also imperative for Roskam to hear what TSA learned from the undercover tests it conducted and how they are using this information to lower the screening failure percentage.
