Which One Is Married To Alan Greenspan?

Can someone please give Brian Williams a roster of Nightly News correspondents and their titles? On Saturday, Brian introduced Andrea Mitchell as the NBC News "chief foreign correspondent". She is actually the chief foreign affairs correspondent. Last June 17, Brian introduced Richard Engel as the NBC News "chief foreign affairs correspondent." He is actually the chief foreign correspondent. Brian sometimes appears in Nightly News promos in which he says, "You rely on us to get it right. Every time." Well, maybe not every time.
