The dark story of the shocking resurgence of white supremacist and nationalist groups, and their path to political power. Six years ago, when Vegas Tenold began reporting from the inner circle of three white power groups in America - the KKK, the National Socialist Movement, and the Traditionalist Workers Party - he found himself in the midst of small, disorganized groups operating well outside the mainstream. But in the last few years, that has all changed. Their racially-motivated violence has been on open display at rallies in Charlottesville, Berkeley, Pikesville, Phoenix, and Boston. In response to economic grievances, anger over the presidency of Barack Obama and the visibility of Black Lives Matter, and egged on by the rhetoric of Donald Trump, membership is rising and national politicians are giving validation to these groups.
