Seven months before a gunman murdered 18 people in Lewiston, Maine, a shooter killed six people at an elementary school in Nashville, Tennessee, three of whom were just 9 years old. That shooting propelled Rep. Justin J. Pearson and two fellow Democrats to protest gun violence on the floor of the State House of Representatives. In response, Republicans in the House voted to expel Pearson, who was reinstated days later, and went on to win reelection. Rep. Pearson — who attended Bowdoin College near Lewiston, Maine — joined Crystal Haynes to call for comprehensive gun reform, as well as social, economic and racial justice. They were also joined by Sharon Scott-Chandler, president and CEO of Action for Boston Community Development.
