"Nation Under Siege": Nina Turner on Highland Park Shooting & Stopping U.S. Gun Violence

Six people were killed and at least two dozen injured when a rooftop gunman armed with a high-powered rifle attacked a Fourth of July parade in the Chicago suburb of Highland Park on Monday morning. The police eventually arrested Robert Crimo III, a 21-year-old white resident of Highland Park and aspiring musician, whose music videos depicted mass murder and school shootings. We speak with Nina Turner, former Ohio state senator and national co-chair of the Bernie Sanders 2020 presidential campaign, who says mass shootings in the U.S. are partly fueled by racism, sexism and toxic masculinity" that equates gun ownership with manhood. We have neglected to deal with a violent past and a violent present in the United States of America," says Turner.
