Editor's note: This entry, posted this morning, is about last night's broadcast.

Nightly News will look a bit different this evening, but not much. I made the decision to locate our broadcast from the Global Headquarters of CNBC -- since our business network is best at covering this, I thought we'd go to where the experts are, instead of having them come to us. They are the finest experts on our lead story tonight: what's being called the closest thing we've seen to a financial and banking meltdown since the Great Depression. There are apparently more components to come -- AIG is in play. These are big names, these are real people and this is real money. And as I write this, the Dow is on a run to the south in a hurry.

Our attention is torn between two giant stories -- both involving suffering and destruction, but of an entirely different kind. We have a slew of correspondents and camera crews in Texas -- and naturally we felt a strong tug toward that story as well. The damage in Galveston is unbelievable, and the desolation in downtown Houston is striking. A whole lot of people are suffering as a result, and our hearts are with them.

So in a few moments we'll depart our 30 Rock headquarters for CNBC headquarters and continue working on tonight's broadcast.
