Anyway - here's Glenn's online interview with Ms. Couric, for those who didn't get a chance to see it (like me) or those who didn't even know about it.
I watched this interview in full. It was fair, generally speaking. You can read very clearly into the ideological differences between the two, and to be honest I believe you get a sense at the end of the interview that Couric has a new-found respect for Beck.
Beck did not allow Couric to play 'gotcha' as she attempted. He offered his website as a place to gather information. If you didn't hear his radio show the day after the "Obama's a racist" comment, go here to listen, just click on the 'free audio' button and it will open in media player. It's about 16 minutes and very informative.
Also, here's a very interesting video clip from around the same time frame.
