Fred Guttenberg, whose daughter was murdered in the Parkland shooting, engaged in a heated exchange with Sen. Marco Rubio on Wednesday night at a CNN town hall.
Why it matters: Rubio was the only Republican on-stage with parents, teachers, and students who were impacted by the shooting. He's received criticism for his response to the shooting, and donations he's received in the past from the National Rifle Association. He told the audience he would support increasing the age requirement to purchase rifles, banning bump stocks, and improving the background check system.
