WASHINGTON (AP) — Navy Secretary Ray Mabus ordered two security reviews Tuesday to look at how well the Navy protects its bases and how accurately it screens its workers, following the mass shooting at the Washington Navy Yard.

A senior defense official said that Defense Secretary Chuck Hagel also intends to order a review of physical security and access at all department installations worldwide as questions swirled Tuesday about the quality of the Pentagon’s security systems and how well the military screens uniformed and civilian workers who have access to some of the country’s most secure buildings.
