WASHINGTON (AP) — President Barack Obama and the first family have lit the national Christmas tree.

Obama is being joined at the annual event by his wife, Michelle, and daughters Malia and Sasha. Mrs. Obama’s mother, Marian Robinson, is also attending.

This year’s ceremony marks the 92nd annual lighting of the Christmas tree just steps from the White House. The National Park Service says the tradition was started by President Calvin Coolidge in 1923.
