The release of a new Government Accountability Office (GAO) report regarding the Department of Homeland Security’s (DHS) continuing efforts to expand the Visa Waiver Program (VWP) prompted Sen. Dianne Feinstein (D-CA) to call a recent hearing of the Senate Judiciary’s Subcommittee on Terrorism, Technology and Homeland Security which she chairs. The hearing offered Feinstein, a frequent critic of the program, an opportunity to question DHS about security issues in the VWP.
