After addressing the House Democratic Caucus late Saturday morning, President Barack Obama will travel to the Camp David presidential retreat in Maryland, where he will spend Saturday night. The decision to leave the White House may suggest that the president does not expect the House to vote on the health care reform bill on Saturday night, though he can return quickly to Washington, D.C., if he needs to. Obama is scheduled to be back at the White House early Sunday afternoon. The president on Friday afternoon traveled to Walter Reed Army Hospital, where he visited with 19 soldiers, three families of soldiers in the intensive care unit and hospital staff. The President also awarded two Purple Hearts. An administration official said the hospital visit was long in the works and was not related to the killings Thursday at Fort Hood Army Base in Texas.
