I found myself in one of those "where were you?" conversations today. You know, the kind we so often have on the anniversaries of major events. In this case, I was with NBC News colleagues discussing how we each learned of, and reacted to, the news that our colleague Tim Russert had died.
While our individual whereabouts on June 13th, 2008 varied widely, we all agreed there was a shared moment of disbelief when we heard the news, and that it is still with us on this one-year anniversary. Tim remains an awfully big presence in our organization, and whenever a particularly juicy political story pops onto the radar, if we're not saying it outloud, one of us is likely thinking it: Tim would have loved getting a piece of this story.
We do have a big political story on the program tonight, but this one is focused on Iran, were anger over President Mahmoud Ahmadinejad's apparent re-election has sent supporters of rival candidate Mir Hossein Mousavi rioting in the streets.
Tonight, a great deal of the communication out of Tehran has been cut off, and in a speech to the nation, Ahmadinejad accused the foreign media of instigating trouble. Our chief foreign correspondent Richard Engel has just left Iran, but not before filing a report on today's violence. We'll have it for you on the program tonight.
I hope you can join us.
