The mass shooting at the Washington Navy Yard is raising new questions about whether there's a problem with security on America's military bases.
A new report from the Pentagon says there is and it's the screening process for contractors.
The report was underway even before Monday's attack. The inspector general found that convicted felons, like Navy Yard shooter Aaron Alexis, routinely gained access to military facilities.
"Mr. Alexis had legitimate access to the Navy Yard as a result of his work as a contractor and he utilized a valid pass to gain entry to the building," Valerie Parlave, head of the FBI's field office in Washington, said Tuesday.
Alexis was first granted secret-level security clearance in 2008. Somehow he was able to keep that clearance despite being discharged in 2011 and facing several run-ins with the law.
Now Defense Secretary Chuck Hagel is ordering U.S. military installations around the world to undergo security reviews.
Meanwhile, lawmakers on the left are using the Navy Yard shooting to revive the debate over tougher gun control.
President Barack Obama is pushing for Congress to revisit new legislation, saying stricter laws could make the United States less vulnerable to such attacks.
"The fact that we do not have a firm enough background check system is something that makes us more vulnerable to these kinds of mass shootings," the president said.
But not everyone agrees. Jesse Jane Duff, with Concerned Veterans for American, told CBN News that more laws aren't the answer.
"I do feel that your senior level staff, non-commissioned officers and your officers should be allowed to carry -- it just would make sense," she said.
Concerned Veterans for America's Jessie Jane Duff, a retired Marine gunnery sergeant, spoke about base security and the immediate calls for gun control, on CBN News Channel, Sept. 17.
The Navy Yard attack has prompted at least three new investigations into government security and background screenings from both the Navy and the White House.
