Bill O’Reilly: Cut his mic. I’m not going to dress you down anymore, out of respect for your father. I won't listen to anymore of your communist propoganda. You are terrible. We will be back in a moment with more of THE FACTOR.
Jeremy Glick: That means we’re done?
Bill O’Reilly: We’re done. I'm not going to do this anymore, you harpie! I'm done.
After the show, O’Reilly told Glick, “Get out, get out of my studio before I tear you to fucking pieces!”
