On the heels of the deadly mass shooting at the Washington Navy Yard, a forthcoming internal government report is expected to find that Navy facilities are cutting corners on security in order to cut costs — leading a Republican congressman to decry “serious security flaws” in the system.

The shooter at the Navy Yard was a former Navy reservist who since leaving the military had been working as a defense contractor. Fox News has learned that Navy Secretary Ray Mabus on Tuesday plans to order a review of security at all Navy and Marine installations.

But Rep. Mike Turner, R-Ohio, chairman of a House Armed Services subcommittee, revealed late Monday that a forthcoming inspector general report will address security procedures at Navy installations. Though that report has not yet been released, Fox News confirms that it determines the Navy is not taking enough security precautions when it comes to outside contractors.
