Obama tees off into birthday weekend with golf

Obama turns 52 on Sunday

WASHINGTON - President Barack Obama is kicking off his birthday weekend with a round of golf at an Air Force base outside Washington.

Obama turns 52 on Sunday.

The president left the White House unusually early on Saturday for the trip to Andrews Air Force Base in Maryland to squeeze in some golfing time before heading to Camp David in the afternoon.

The White House said there were three golfing foursomes, including Obama friends from Hawaii and Chicago, and current and former staffers.

Some of Obama's friends are expected to join him at the Camp David presidential retreat in Maryland's Catoctin Mountains.

Obama is scheduled to return to the White House on Sunday.

So far, Obama has taken 87 days off, compared with 399 days for Bush at a similar period in his presidency, according to CBS News's Mark Knoller, who keeps detailed records of presidential travel.
