Gateway Pundit has the story, from O'Reilly:
Sgt. Brian Fountaine: To be honest, if I knew that they were a liberal newspaper in the fist place, I wouldn't even had talked to them. But, I told him what I thought and I think he just spun it way out of control and he put it to his newspaper's point of view which I did not know was antiwar.
Bill O'Reilly: Alright, give me a specific about what you told them and how it played out.
Sgt. Brian Fountaine: I'm not sure about specifics but something off the top of my head, even the headline. It made it sound like I'm against the war and I'm against everything that's going on over there, which isn't true!
