Journalist Eli Saslow says white nationalism inspired the man who killed 11 at a Pittsburgh synagogue: “In the horrific hierarchy of white nationalist beliefs, they really consider Jews their primary enemy.” Saslow spoke with Terry Gross Monday morning about the tragedy and its “straight line” to the white nationalist movement.

Also, we’ll listen back to an excerpt of the interview with Saslow and former white nationalist Derek Black from September. Saslow’s book, ‘Rising Out of Hatred,’ focuses on Derek, who was once a leading voice in the white nationalist movement but has since denounced his views.
