Obama lied about his uncle liberating Nazi camps?

He claimed it was Auschwitz not Buchenwald, he claimed Uncle when it was a great Uncle. Both are lies. If Hillary had said this then the blogs and media would be going nuts, a lie is telling something that you know is not true. He knew he has NO uncle and he also knows that Auschwitz was liberated by the Russians. That would make the case that he embellished his story for effect or lied.
