Today, Celeste and John speak with U.S. Sen. Chris Murphy, the Connecticut Democrat who led a 15-hour filibuster to force lawmakers to take action on stronger gun control regulations after 49 people were gunned down at a gay nightclub in Orlando, Florida. Murphy's measure also came as Jo Cox, a U.K. Labour Party member of Parliament, was murdered in a savage shooting and stabbing attack in her home district amid the tensions of the Brexit vote. Murphy expresses his anger and frustration — but also his hope for change — as he and like-minded legislators battle the gun lobby for measures including a ban on gun sales to people on the terror no-fly watch list.
