John Legend gets into Twitter feud with Donald Trump Jr.

John Legend has no patience for Donald Trump Jr.'s mockery of protestors at his father's campaign rallies.

"When asked why they were protesting couldn't even answer. The participation medal/micro-aggression generation is pretty sad!" Trump Jr. tweeted Friday night.

"I think they were protesting your racist father," Legend fired back. "This isn't complicated."

When Trump Jr. dismissed Legend's comment saying "That can't be the answer for everything you don't like," the singer said it only applies in one situation: "It's just the answer when racist racists are saying racist (expletive) and are endorsed by the KKK."

When a Trump supporter accused Legend, a graduate of the University of Pennsylvania, of being uneducated, he noted, "the Donalds and I graduated from the same University, funny enough."
