New American Nazis: Inside the White Supremacist Movement That Fueled Pittsburgh Synagogue Shooting

Neo-Nazis are on the rise in America. Nearly a month after a gunman killed eleven Jewish worshipers at the Tree of Life synagogue in Pittsburgh, we look at the violent hate groups that helped fuel the massacre. On the same day that shooter Robert Bowers opened fire in the synagogue, a neo-Nazi named Edward Clark that Bowers had been communicating with online took his own life in Washington, D.C. The man's brother, Jeffrey Clark, has since been arrested on weapons charges. The brothers were both linked to the violent white supremacist group Atomwaffen. We speak with A.C. Thompson, correspondent for FRONTLINE PBS and reporter for ProPublica. His investigation "Documenting Hate: New American Nazis" premieres tonight on PBS stations and online.
