In the incident involving McConnell a Capitol Visitor Center worker discovered the firearm in a visitor center stall. In the Boehner incident, a child of roughly 7-8 years of age found the firearm in Speaker's Suite bathroom.
In addition, there was a third incident reported just weeks ago, where a janitor found another loaded gun while cleaning the Capitol Police Complex.
In the wake of these incidents, officials have noticed. Pete Sessions (R-TX) called for Capitol Police to "retrain everyone who carries a firearm", while Candice Miller (R-MI) called for an overhaul of the chain of command.
