On today’s “Morning Joe,” journalist Cokie Roberts sparred with GOP front-runner Donald Trump after Roberts asked him if he’s “proud” of the current “political discourse,” citing anecdotal reports of white kids taunting “their darker skinned classmates.”

Trump replied with, “I think your question is a very nasty question and I’m not proud of it because I didn’t even hear of it.”

Watch here:

What a dumb question. Whatever you think of Donald Trump, he’s not responsible for the behavior of every kid in America.
