Khamenei Letter to Obama?

So, as the Wall Street Journal initially reported on Feb. 13th, did Iran's Supreme leader the President a letter, or not (or not)?    Per the WSJ: "Neither the White House nor the Iranian government has officially confirmed any correspondence between the two. Iranian officials, in recent months, though, have told Tehran’s state media that some of Mr. Obama’s letters were answered, without specifying by whom."  Per Iran, "This claim by the American newspaper, Wall Street Journal, is an unprofessional media game,” Iran’s Foreign Ministry Spokeswoman Marzieh Afkham said in a statement on Sunday."
