Rudy Giuliani left Good Morning America viewers befuddled Friday morning when the mayor of New York City during the 9/11 attacks said that the U.S. had "no domestic attacks under Bush," but "had one under Obama." Even more curious was when GMA interviewer George Stephanopoulos didn't press him on the error. Stephanopoulos has apologized on his blog, saying, "Whatever the Mayor meant, it’s not what he said. All of you who have pointed out that I should have pressed him on that misstatement in the moment are right. My mistake, my responsibility."
