"What happened last year as families in Highland Park gathered to celebrate the Fourth of July is nothing short of an atrocity. That gunman, who shot off more than 80 rounds in 60 seconds, destroyed families, paralyzed children, and scarred a community for a lifetime. My heart still aches for Highland Park, and we must seek pathways to preventing the next heartbreaking shooting. I spoke with Illinois-based physicians associated with March Fourth today about how we can build support in Congress for an assault weapons ban and how we can take steps to address gun violence as a major public health threat."
