CNN has learned Defense Secretary Chuck Hagel is ordering a worldwide review of physical security measures at all US military installations in the wake of the attack at the Washington Navy Yard.
A senior Pentagon official tells CNN Hagel will order the military to look at all existing security measures to see if they are sufficient and to determine what other measures may be needed. Still to be determined is who will be put in charge of the review and the deadline for reporting back to Hagel.
At the same time, the Pentagon is still trying to determine what it needs to do to begin a parallel review of security clearances and access standards for contractors and other employees, according to a Defense Department official. Some elements of clearance procedures are handled by other parts of the government so coordination will be required, but the official said it’s expected some review of that element will also take place.
This follow an earlier confirmation from the Navy that it was beginning a similar physical security review at all of its installations.
