The U.S. Capitol Police arrested a man at a security checkpoint in Washington on Friday after he flashed what an officer described as an “unauthorized” inauguration credential and a search of his truck found an unregistered handgun and more than 500 rounds of ammunition, the authorities said.
A federal law enforcement official said that the man, Wesley A. Beeler, 31, worked as a contractor, and that his credential was not fake, but was not recognized by the police officer. The official spoke on the condition of anonymity because he was not authorized to discuss the arrest.
