If you thought you knew all there was to know about White House Chief of Staff Rahm Emanuel (or if you know nothing about him), there's this -- following his decision to deliver a very personal commencement address this weekend in Washington.

And as for this reporter, our NBC Affiliates are in town -- my elective time is devoted to them, and so today we'll have to keep this short. I hope you can join us for the broadcast tonight...especially our final story. We'll see you then.
