Three people are suing Republican presidential candidate Donald Trump, claiming they were subjected to racial slurs at one of his rallies in Kentucky, NBC News reported.
They allege he encourages an atmosphere of violence.
The suit was filed Thursday on behalf of three protesters seen being pushed by angry crowd members at a March 1 Louisville, Kentucky, rally.

"Each time he said 'get them out,' Trump intended for his supporters to use unwanted, harmful physical violence to remove protesters," the suit reads.
Violence at Trump rallies, at least two of which involved audience members sucker punching protesters as they were being led away, have raised questions about whether the Republican front-runner's speeches and tone are inciting supporters. Trump has denied that he condones violence.
