U.S. President Barack Obama is opening the door to the possibility of a resumption of White House tours, if it can be worked out. President Obama says in an interview broadcast with ABC News Wednesday that the decision to cancel the tours in the wake of budget cuts was made by the Secret Service, citing the need to furlough some employees. Revealing he\'s trying to ease the no-tour policy, Obama says he\'s talked to the Secret Service about restoring some visits.
