A member of Rep. Joe Morelle's (D-NY) staff was arrested Monday after he allegedly brought ammunition and a high-capacity magazine onto the Capitol grounds.
Fox News correspondent Chad Pergram reported that U.S. Capitol police arrested 38-year-old Michael Hopkins after an X-ray screening found what appeared to be ammunition as he was entering the Cannon House Office Building, the oldest office building in Congress.
"After a hand search of the bag, officers found four ammunition magazines and eleven rounds of ammunition," a statement from the Capitol Police said, according to Pergram. "The staffer told the officers that he forgot the ammunition was in the bag."
Hopkins was expected to be charged with unlawful possession of ammunition and possession of a high-capacity magazine.
