The "Justice for J6" rally wrapped up Saturday afternoon after about an hour of speeches, without any major known incidents.
Authorities had warned of possible threats of violence at the event, and Capitol Police officers could be seen in riot gear standing on the perimeter of the crowd as people gathered in front of the U.S. Capitol.

The Capitol Police Civil Disturbance Unit also responded to a group of protestors and counterprotestors near the Capitol and "separated the groups without incident," police said.
