Here is a video with Margaret.
http://www.c-spanvideo.org/program/id/216620Unbelievably, I saw this and I didn't get a good look at the woman in the group. They were talking to one of the guys. So I just switched the channel.

By the way, catch the show "Vanity Fair: Covering the Crisis" this weekend. Maggie appears as they go into commercials. I assume at the beginning too. I caught it from about 5 minutes into it. Also we see her at the end when they take questions from the audience. Some good shots of her standing up and one or two moments of her from behind as well. She is wearing this dress:

Interestingly, the C-Span video is at Margaret's alma mater, the University of Virginia. Here are the highlights:
2:40 Margaret gives us a smile during her introduction. Well, she is being introduced. Interesting jacket. You do see some long shots of her in the group. Alas, she is wearing pants.
11:45 Margaret speaks for about 3 minutes.
21:50 Margaret speaks for about 2 and a half minutes.
34:40 Margaret speaks for about a minute and 20 seconds. Looks like a cute woman sitting in the front row too.
43:10 Margaret speaks for 1:20. I like how the camera lingers on her even after she is done.
58:40 Margaret speaks and then the guy is speaking and we see Margaret listening. About 1:20. Looks like our Bloomberg babe has a little cold. Sniff sniff.
71:15 to the end. Margaret makes a sad but funny point on the nature of news. She laughs, speaks and smiles a bit. A good ending.
