Trump just said out loud that his traveling doctors ignore sick people in the crowd. His exact words: "You know what they call them? Collateral damage." Then he pointed at someone in the audience and said he looks like he's about to have a heart attack, and if he did, the doctors would leave him alone. This isn't a gaffe. This is Trump describing his medical team's actual protocol and calling abandoned human beings "collateral damage" while joking about it.
