President Barack Obama took advantage of another sunny day in Windward Oahu to play golf Friday, his fourth golf outing in a week as he nears the end of his 10-day Hawaii vacation.

Obama played the Kaneohe Klipper course on Marine Corps Base Hawaii for the third time, again with Hawaii friends Mike Ramos, Greg Orme and Bobby Titcomb. He played at the Koolau Golf Club on Wednesday.

Obama’s holiday did not go unnoticed Friday by Republican presidential hopeful Mitt Romney, who was campaigning in Iowa and again criticized the president for golfing while on vacation, The Associated Press reported.

"He’s in Hawaii right now. We’re in the cold, in the rain, in the wind because we care about America," Romney said, speaking to several hundred supporters in the parking lot of a grocery store in West Des Moines. "He just finished his 90th round of golf. We have 25 million Americans who are out of work, stopped looking for work or are underemployed. Home values have come down. The median income in America in the last four years has dropped by 10 percent."

Earlier Friday the president maintained his daily routine by working out at the gym at Marine Corps Base Hawaii, a short drive from his Kailua vacation compound.

Obama and his family are scheduled to return to Washington on Monday.
