Washington Celebrates Christmas with Tree Lightings

People will be swarming the nation's capital Thursday for the National Christmas Tree Lighting Ceremony. 

This marks the 94th annual lighting ceremony at the White House. The first National Christmas Tree was lit in 1923 by President Calvin Coolidge.

The 2015 Christmas tree ceremony paid homage to the National Park Service centennial.

This year will be a star-studded event with performances from stars like Kelly Clarkson and Yolanda Adams. 

Meanwhile across town, the sounds of Christmas carols filled the air as D.C.'s Union Station lit their Christmas tree as part of the annual Norwegian Christmas ceremony. The event featured songs in both English and Norwegian and a visit from jolly old Saint Nick.
 
A 32-foot tree decked the halls of the historic landmark and was adorned with 20,000 lights. This is the 20th year for the Norwegian Christmas at Union Station. The original tree was given as a gift from Norway to thank the U.S. for their help in World War II.
