Washington ? Add this to the list of duties for President Barack Obama and his wife, Michelle: having enough candy to satisfy 2,000 trick-or-treaters banging on the White House door.

The White House said Friday the Obamas will give a Halloween welcome to hundreds of children from schools in Washington and the surrounding Maryland and Virginia suburbs. The trick-or-treaters will come to the front door today just as they would at any other house — except it will be the soaring North Portico of the White House.
