Khan told CNN's Jim Acosta on "State of the Union" that he hopes Trump's family will "teach him some empathy."
"He is a black soul, and this is totally unfit for the leadership of this country," Khan said. "The love and affection that we have received affirms that our grief -- that our experience in this country has been correct and positive. The world is receiving us like we have never seen. They have seen the blackness of his character, of his soul."
