A notorious white supremacist movement leader is among three men who are facing criminal charges for assaulting and verbally harassing a black female protester at a Donald Trump rally in Louisville in March.

According to Louisville TV news station WDRB, Matthew Heimbach, the well-known leader of the racist and white nationalist Traditionalist Youth Network, has been issued a criminal summons to appear in Jefferson District Court. He faces charges for harassment with physical contact toward Shiya Nwanguma, one of the anti-Trump protesters at the March rally. WDRB notes the court also issued criminal summons for Alvin Bamberger, a 75-year-old Ohio resident and Korean War Veterans Association member, and Indiana resident Joseph Pryor.

As Raw Story previously reported in March, Nwanguma, a black woman and University of Louisville student, said she was kicked out of the Trump rally after being shoved and screamed at by Heimbach and other Trump supporters.

“I was called a n****r and a c*nt and got kicked out,” Nwanguma said. “They were pushing and shoving at me, cursing at me, yelling at me, called me every name in the book. They’re disgusting and dangerous.”

As WDRB reports, Nwanguma has filed a lawsuit against Heimbach, Bamberger and Pryor, addressing the three men’s racist and sexist slurs against her and alleging they repeatedly assaulted her.

Heimbach, who has publicly asserted that he’s standing up for the white race, explained on his website that Nwanguma was trying to disrupt the rally. But Nwanguma said she was protesting non-violently, holding a sign depicting Trump as a pig.

Nwanguma told WFPL, the Louisville NPR station, that rally attendees were already trying to take the sign from her when Trump saw her from the podium and told the crowd to kick her out.
