This federal construction project has dragged on through four administrations

The Homeland Security Department's headquarters project might be one of the longest-running construction programs in government history. Planning started more than 17 years ago. The latest estimates peg the completion date at 2027, another five years. Now, the Government Accountability Office reports the latest cost and schedule estimates lack detail and, perhaps, reliability. Federal Drive host got some details on the mater from Chris Currie, GAO's director for Homeland Security and Justice issues.
