The issue of gun violence is personal to me. I met my husband working to pass the Manchin-Toomey bill in the U.S. Senate that would have expanded mandatory background checks on most commercial gun sales. My husband was Rep. Gabrielle Giffords’ legislative director when she was shot at a public event in 2011. I am the mother of a girl who will be going to kindergarten in just a year, and another a few years after that — I don’t want them or any of our kids living in a world where gun safety drills are a constant part of their educational experience.
