Elizabeth Neumann served as the assistant secretary for threat prevention and security policy at the Department of Homeland Security. She has recently been speaking out about President Trump and, among other things, his failure of leadership with respect to the threat of white supremacist violence. In the course of doing so, she made reference to a book by Kathleen Belew, a historian at the University of Chicago: "Bring the War Home: The White Power Movement and Paramilitary America," a history of violent white power movements in the modern United States. Elizabeth and Kathleen joined Benjamin Wittes to discuss the interactions of policy and the history that Belew describes. Why have we underestimated this threat for so long? How has it come to be one of the foremost threats that DHS faces? And what can we do about it, given the First Amendment? See acast.com/privacy for privacy and opt-out information.
