Plenty of Republicans don't consider Trump "one of their own".
Anonymous GOP Congressman: "He gets up in the morning, he sh*ts on Twitter, he sh*ts on us, he sh*ts on his staff, and then he hits golf balls."
Another: “If we're going to lose because of him, we might as well impeach the motherf**ker. Take him out with us and let Mike [Pence] take over.”
