While President Barack Obama is departing Hawaii late Saturday, Mrs. Obama is staying behind to spend time with friends ahead of her upcoming 50th birthday party. The White House says the extra time in the islands is part of Mrs. Obama's birthday gift from the president.
The first lady turns 50 on Jan. 17. The White House did not say when she planned to return to Washington.
The Obamas' daughters, Malia and Sasha, are returning to the White House with their father. They're scheduled to arrive in Washington Sunday morning after a two week vacation.
