"Next time, we might have to kill him"

INSIDE EDITION tracked down the supporter, 78-year-old John McGraw, who was unrepentant.

When asked if he liked the rally, he said: “You bet I liked it. Knocking the hell out of that big mouth.”

And when asked why he punched the protester, he said: “Number one, we don’t know if he’s ISIS. We don’t know who he is, but we know he’s not acting like an American, cussing me… If he wants it laid out, I laid it out.”

He added: “Yes, he deserved it. The next time we see him, we might have to kill him. We don’t know who he is. He might be with a terrorist organization.”
