Where did O'Reilly call him a punk?
The "O'Reilly a liar" part evidently refers to O'Reilly claiming to have seen the evidence proving Zero's alleged birth in Hawaii. When pressed, BOR admitted that he hadn't seen it, but his staff had. The story deteriorated from there.
Glenn Beck, OTOH, calls birthers "morons". Of course, Beck thinks that Mitt Romney is "the guy who's gonna save America".
