My personal impression was that Mel has been too busy to keep up with these things and that Sean was looking forward to enlighten him when they had more time. ""It's all to do with these weapons [of mass destruction] that we can't seem to find, and why did we go over there [to Iraq]."
I have listened to this interview twice, and I can't remember hearing the underlined part at the end either time.
I didn't hear it either, I don't believe he said it at all. Another mis-representation from the press.
