The best part of Katie Couric's broadcast last night, somehow, didn't even make it to air.

She sat down with White House foe Scott McClellan to talk about his new book, and she actually proved to be wearing her Reporter Gravitas Hat:

Couric: Weren't you the ultimate complicit enabler, though? I asked a tough question before the Iraq War and you personally called an executive at NBC News and you threatened to deny access to us.

McClellan: I did?

Couric: Yes, you did, once the war began.

McClellan: Me personally? I don't, I don't remember that.

Couric: But did you strong-arm people into not questioning the administration?

McClellan: My style usually wasn't that way.

Couric: Well, it was you who made the call.

McClellan: I just, I just don't remember that. That may be but I certainly don't remember that incident. In terms of my style of working with reporters, it was usually straightforward when we were dealing with each other; I think I had that reputation with White House reporters. I just don't recall that specific incident.

That part of their conversation, while appearing in the show's transcript, did not appear on TV. [TVN]

Who knows. Maybe Katie Couric actually has the most interesting evening news broadcast around, but producers just hide all the good parts.
