White House Christmas: Obama Family Lights The National Christmas Tree (PHOTOS)

Early Thursday evening the Obamas and the Bidens gathered to light the National Christmas Tree. "Ho! It worked," exclaimed President Obama after pressing the button to switch on the lights.

Michelle Obama read aloud from "T'was the Night Before Christmas."
