The president is scheduled to host Ukrainian Prime Minister Arseniy Yatsenyuk at the White House on Wednesday.
The White House says Obama squeezed in another round of golf Sunday on one of the courses at the exclusive Ocean Reef Club on Key Largo, where the family was staying.
The foursome included sportscaster and former NFL wide receiver Ahmad Rashad, former NBA player Alonzo Mourning and Cyrus Walker, a cousin of senior White House adviser Valerie Jarrett. Obama teed off with the same group on Saturday.
Obama, his wife, Michelle, and their daughters, Malia and Sasha, returned to the White House late Sunday afternoon.
The Obama family arrived in Florida on Friday.
