WASHINGTON, Dec. 1 (UPI) -- The first family lit the National Christmas Tree in Washington on Thursday.
It was the final time they will light the three in Obama's presidency.
Before hitting the lights, the first lady read aloud "The Night Before Christmas" to children who had gathered at the site.
Lighting the national tree is a tradition the president of the United States undertakes every holiday season.
The ceremony also rounded out the National Park Service's Centennial year, which the president has touted all year long.
