The National Christmas Tree Lighting is a ceremony celebrated in the United States, around a large evergreen tree decorated for Christmas at The White House. The lighting of the tree is an annual event held in early December since 1923.
On December 1, 2011, Kermit the Frog helped the National Park Rangers decorate the tree, joined Michelle Obama in a reading of "The Night Before Christmas" by Clement C. Moore (YouTube), and sang "Rudolph the Red-Nosed Reindeer" with Santa Claus (performed by Brad Oscar).
Abby Cadabby appeared at the event on December 6, 2013, reading "The Night Before Christmas" with Michelle Obama.
