A California man was sentenced on Friday to 20 years in prison for attacking police officers with flagpoles and other items during the Capitol riot in 2021, marking the second-longest prison sentence handed down in Jan. 6 cases.

David Dempsey, who wore an American flag gaiter that covered his face during the riot, pleaded guilty to two charges of assaulting police officers. He admitted to going on a violent spree in the Capitol tunnel during which he hit police with poles and other makeshift weapons, pepper sprayed police, and caused “significant injury” to two officers.
