'You are no longer welcome': Cops at Trump event boot peaceful black professor wearing headscarf

Two black men said this week that Donald Trump's campaign ordered Secret Service and law enforcement officers to remove them from a rally in Clemson, South Carolina for no apparent reason.

In a video posted to Facebook, Clemson Professor Chenjerai Kumanyika explains that he and a friend, A.D. Carson, had no problems being cleared by security at Trump's Tuesday rally.

"I stood peacefully observing Trump's speech," Kumanyika says. "I remained quiet and calm the entire time I was there and never spoke to anyone other than A.D."

According to the social activist, police and Secret Service agents began following him when he got up from his seat.

"Eventually, several police officers dressed in military gear grabbed my arm and told me to leave the venue immediately."

The video shows over half a dozen officers and Secret Service agents escorting the two men from the venue.

"I'm leaving, I'm not arguing with you," Kumanyika, who is wearing a headscarf, tells one of the officers. "I just want to know why."

Outside the arena, one officer offers an explanation for the incident.

"The Trump campaign or the Trump people said that you are no longer welcome," the officer says.

"So, it's not you?" Kumanyika asks.

"No," the officer replies.
