In the wake of the deadly anti-Semitic attack at the Tree of Life synagogue in Pittsburgh, FRONTLINE and ProPublica present a new investigation into white supremacist groups in America – in particular, a neo-Nazi group, Atomwaffen Division, that has actively recruited inside the U.S. military. Continuing FRONTLINE and ProPublica’s reporting on violent white supremacists in the U.S. (which has helped lead to multiple arrests), this joint investigation shows the group’s terrorist objectives and how it gained strength after the 2017 Charlottesville rally.
