Tiger Woods joined the president at the Floridian, a secluded yacht and golf club on the state's Treasure Coast.
The White House says the group also included Jim Crane, the Houston businessman who owns the resort and baseball's Houston Astros, and U.S. Trade Representative Ron Kirk.
Obama is spending the long President's Day weekend at the Floridian and is expected to return to Washington on Monday. First lady Michelle Obama and daughters Malia and Sasha are on an annual ski vacation out West.
On Saturday, Obama got some instruction and played a few holes with Butch Harmon, Woods' former swing coach.
