I'm back in New York tonight for Nightly News after a safe journey out of Haiti early Thursday.
My colleagues Ron Allen and Michelle Kosinski remain there, and both will be on tonight's broadcast.
Much has been made of Haiti's declaration that the search and rescue phase is over, especially since a man was just found alive 11 days after the earthquake. Obviously, search efforts are still going on, but officials at some point have to make those tough calls involving survival odds, allocation of resources and growing health and safety concerns.
