Humayun Khan, a slain Muslim American combatant, again trashed Donald Trump and his intemperance and seeming anti-Muslim disdain. “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.”
