President Barack Obama and First Lady Michelle Obama handed out Halloween treats as they welcomed local children and children of military families to ‘trick-or-treat’ on the South Lawn of the White House in Washington, Thursday, Oct. 31, 2013. The White House canceled its Halloween celebration last year in the aftermath of Superstorm Sandy. Trick-or-treaters were greeted by musicians and costumed entertainers. Children were given a mix of sweet and healthy treats in their goody bags.
