US Capitol Police arrest Democrat congressman's staffer after finding ammunition in bag

The U.S. Capitol Police arrested a staff member in New York Democratic Rep. Joe Morelle's office on Capitol Hill Thursday morning, according to a statement released on Monday.

"At approximately 8:45 a.m., a House staffer entered the Cannon House Office Building and put his bag through screening. USCP officers noticed what appeared to be ammunition on the x-ray screen," Capitol Police said, according to Fox News.

"After a hand search of the bag, officers found four ammunition magazines and eleven rounds of ammunition. The staffer told the officers that he forgot the ammunition was in the bag," the statement continued.

Michael Hopkins, 38, faces charges for "unlawful possession of ammunition, including one charge for possession of a high-capacity magazine," Fox News reported.

Morelle's office said that it is "fully committed to cooperating with the investigation," according to WROC.
