One of my favorite things about filling in for Brian Williams on NBC Nightly News, is actually what happens behind-the- scenes.

When, in the afternoon meetings the broadcast's very smart talents go over the rundown of stories, there is yes passion and intensity, but also an easy banter and even warm laughter.

This is a quietly confident team, that includes a surprising number of young people, and what's more, they are remarkably NICE to each other.

(For example when producer Amber Payne won a talent competition recently, people here didn't just congratulate her..together, they watched her entire singing performance and clapped for her not once but THREE times.)

All of which is to say that it is a real pleasure to keep Brian's chair warm again tonight. He is back on monday by the way.

As for what we are working on tonight, get ready for, among other stories:

-More new details on the health care bill, which is still gaining support, including when coverage for pre-existing conditions would kick in,

-Today's images from Haiti's Port-au-Prince, where the rainy season is raising new health concerns,

-New questions about the Pope, and how he handled an alleged child abuse scandal in the Catholic Church in Germany,

-And a story we ran out of time for last night, about a 77 year-old nun who has a lot of poignant reasons to celebrate today's win by Xavier in the NCAA tournament today.

On a final note, I was invited to meet with a group of journalism students from Emerson College this afternoon. And their questions, about how to become good reporters, and how to do stories that make a difference, made me feel we may not have to worry so much about the future of journalism.

See you tonight.
