From the Guardian: The Southern Poverty Law Center, an Alabama-based watchdog that monitors hate groups, calls the Traditionalist Workers party (TWP) a white nationalist group.
The march was organized by the Golden State Skinheads, a California affiliate of the group. Their national chairman of the TWP is Heimbach, a 25-year-old former radical rightwing student organizer whom the SPLC describes as “the face of a new generation of white nationalists”.
In a post to the organization’s website, Heimbach wrote that he was aware of plans to counter-protest but said: “After carefully weighing the pros and cons, we have decided that this would be our Thermopylae, no matter what it costs. We will defend ourselves by any means necessary, and if the police in Sacramento do not protect our right to speak, we will do it ourselves.”
Heimbach was accused of assaulting a black woman at a Donald Trump rally in Louisville, Kentucky, earlier this year. He was named in a lawsuit filed by protesters against the presidential candidate, and acknowledged in an online post, as described in the lawsuit, that he had shoved her. The incident was caught on video.
