Parkland parents pushing politicians to address gun violence
Students at Marjory Stoneman Douglas High School in Parkland, Florida, are heading back to campus. Many student-activists from the school wrapped up their nationwide Road to Change bus tour in Newtown, Connecticut. They're calling for common sense gun reform after 17 of their classmates were shot and killed at the high school in February. One of the victims killed was senior Joaquin Oliver. His parents, Manuel and Patricia, joined CBSN to talk about their push for change in the face of tragedy.
