Two weekend events organized by Democratic groups seek out not only ways to respond to the policies of President Donald Trump, but are also intended to sign up volunteers for community groups. Organizers of Saturday's "Building a Progressive Politics in the Trump Era" include Urbana Alderman Aaron Ammons, while Sunday's "First We Marched, Now We Huddle" is seen as the Champaign County Young Democrats' follow-up to the Women's March held in downtown Champaign in January.
