(Washington, DC) -- Senators are looking to tighten security procedures after last month's deadly shooting spree at the Washington Navy Yard. A hearing of the Senate Homeland Security Committee is looking at the adequacy of background checks. Opening the hearing, Delaware Democrat Tom Carper suggested the system is "fundamentally flawed." Oklahoma Republican Tom Coburn called the system "broken."
Aaron Alexis, a private contractor working for the Navy, shot and killed a dozen people at the Navy Yard before being shot and killed by police. Montana Democrat Jon Tester said the victims were "killed by a man with a history of mental illness, a pattern of violent behavior and a criminal record." Tester noted that Alexis was cleared by the federal government after a background check by a private contractor.
