U.S. House members will resume discussions this week about federal building security in the wake of the shooting at the Pentagon — the latest attack on federal facilities across the country. The House subcommittee on the federal workforce plans to focus especially on how federal agencies are sharing tips on threats with local law enforcement agencies, which could be unfamiliar with the tenants and security efforts at government buildings in their jurisdictions. Separately, aides to the chairman of the Homeland Security and Governmental Affairs Committee said he plans to introduce a bill with proposed federal security changes in April, after delaying it last fall to account for the shootings at Fort Hood, Texas. “These recent assaults on federal employees seem to be motivated by a deep-seated and irrational hostility against the government,” the Senator said late last week.
