About 150 "Impeach Trump" members and 50 pro-Trump members held separate marches Sunday morning.
Police say a group of Trump supporters tried to enter a bar in the city after the march when they were confronted by anti-Trump demonstrators.
A fight broke out, during which a pro-Trump protester and a police officer were assaulted, AP reported.
Two anti-Trump demonstrators were charged with assaulting the Trump supporter. Police say the Trump supporter suffered a minor mouth injury. A third person was charged with assaulting the police officer, and a fourth person was issued a citation.
