No president has ever kept his golf game more secret, writes Don Van Natta Jr. in an article for ESPN magazine about President Obama’s golf habit.

Just as Obama the president relies on a coterie of White House advisers, Obama the golfer plays with the same handful of people — a tight circle of junior White House aides and advisers, most often body man Marvin Nicholson (a former caddie at Augusta National) and confidential assistant Eugene Kang. When on vacation in Hawaii, the president plays with buddies from Chicago and a few old Hawaii pals. None of those people would comment for this story. The first rule of golf club: Don’t talk about golf club.

Another interesting fact in the article: Since becoming president Obama has only played golf with one journalist: Thomas Friedman, an op-ed columnist for The New York Times. Also interesting is that President Dwight Eisenhower played nearly 800 rounds during his two terms in office – a habit that Democrats predictably criticized.
