I have to listen to the 3rd hour online streaming. No mention of the "going into Iraq" part that I could hear eather. My AM station drops out at around 6:00 p.m. and they broadcast the 3rd hour after their "6 o'clock news hour". On that day, the AM signal stayed up, so I listened to the interview again (twice within 2 hours).
The whole issue of politics was the shortest part of the interview which lasted about 2 minutes [more or less]. Sean asked Mel if he was conservative (actually said you are aren't you?) and support the President, to which Mel replied somethinng to the effect that he was gennerally supportive and that the President has done a lot of great things in his opinion, but that he'd been having his doubts of late over the whole WMDs, and them not being found thing...to which Sean replied that they were probably shipped to Syria and that he would like to enlighten him further some other time. So, as long as that took to read was about as long as the whole "political" part of the interview lasted if I remember accurately.
