A Heritage Foundation staffer was stopped from entering a Senate office building after authorities say they found ammunition and suspected drugs in his briefcase. Matthew Christopher Wingate was detained by Capitol Police on July 14 after allegedly attempting to pass through security at the Russell Senate Office Building. The Texas native held a valid license to carry a firearm in Washington, D.C., but firearms and related weapons are prohibited inside Senate office buildings, and he was subsequently arrested and taken into custody. Capitol police officers stand guard outside the Russell Senate Office Building. Wingate was released following his arrest on the misdemeanor charge and is scheduled to appear in court on Aug. 27, according to court records.
