One of President Obama’s oldest friends, Robert Titcomb, was arrested Monday in Honolulu for soliciting a prostitute. He has since been released on $500 bail. Titcomb, 49, attended the Punahou School in Honolulu with Obama in the 1970s, and the pair have remained friends since, with Obama’s family attending barbeques at Titcomb’s house in Waialua. Obama and Titcomb frequently play golf, and they spent time together during Obama’s Christmas vacation in Hawaii. Titcomb is also frequently mentioned in Obama’s memoir, Dreams From My Father.
