I doubt if this report is true. Not in any ther news source, including Turkish. I doubt if Obama, a lawyer, would be so crass so as to advise anyone against an open investigation so as as not to be "hurt" by facts. Give me a break. I do wish he had bigger balls though, maybe Erdogan can lend him one, he has too many.
