WASHINGTON (AP) -- President Barack Obama is doing something unusual with his summer vacation on Martha’s Vineyard.

He’ll return to Washington midway through the two-week getaway to attend "in-person meetings" with White House staff before heading back to the island.

Obama’s spokesman says the meetings aren’t related to any "emerging situation," but he declines to say who the president will be meeting with or what the meetings are about.

Aides long have argued that Obama is president at all times and can do the job from wherever he is.

Obama is scheduled to arrive on the Massachusetts island on Saturday and return to Washington a week later, on Sunday, Aug. 17.

After the meetings, Obama is scheduled to return to Martha’s Vineyard on Aug. 19 for the remaining five days of the vacation.
