Obamas greet trick-or-treaters at the White House

U.S. President Barack Obama and First Lady Michelle Obama welcomed their most important guests of the year: Halloween trick-or-treaters.

Thousands of disguised sailors, superheroes, soldiers, princesses and other costumed characters flooded in the White House, which was decorated with giant pumpkins, to be treated with chocolate candies and butter cookies and to meet the President and the First Lady.

The only trick? The Obamas dressed as themselves this Halloween.
