The lawsuit accuses Trump of encouraging an atmosphere of violence at his rallies by urging his supporters to physically remove demonstrators and offering to pay their legal bills if they are arrested for doing so.
The suit was filed on behalf of high school student Henry Brousseau, 17, activist Molly Shah, 36, and college student Kashiya Nwanguma, 21, according to the report.
Video of white protesters jostling and shoving Nwanguma, who is black, at the March rally in Louisville went viral at the time. She alleged afterwards that the rally attendees called her “a nigger and a cunt.”
Matthew Heimbach, a prominent white nationalist, later took credit in a blog post for helping to “drive out” the protester from the event.
NBC News reported the suit alleges that Brosseau was punched by a member of Heimbach’s group, the Traditionalist Youth Network, and that Shah was shoved. It also argues Trump helped foster this chaotic, violent ambiance by repeatedly telling rally attendees to “get ‘em out of here."
"Each time he said 'get them out,' Trump intended for his supporters to use unwanted, harmful physical violence to remove protesters," the suit reads, as quoted by NBC News.
Violence is a fairly common occurrence at Trump events. Two protesters were punched in the head at his campaign rallies in March, and a 15-year-old girl was pepper-sprayed in the face Tuesday outside a Janesville, Wisconsin rally.
It's not the first time the GOP frontrunner has faced a lawsuit stemming from such a violent incident, either. In September, protesters of Mexican descent sued Trump, his campaign, his company and chief of security Keith Schiller after Schiller allegedly assaulted them as they stood outside Trump Tower with a sign reading “TRUMP: Make America Racist Again.”
