Mark Goldstein, Director of Physical Infrastructure Issues, GAO

But, as Mark Goldstein, GAO’s director of physical infrastructure issues, explained on the Federal Drive with Tom Temin, more security means a greater workload for the Federal Protective Service. Reports from the Government Accountability Office show the small agency isn’t always prepared for new threats.
