I want to see more than a BC. There might not be any ‘controlling legal authority’ that could compel disclosure, but short of being blinded by ideology, I can’t see how any thinking person would not be very suspicious.
Early on, I wasn't a “birther,” but as I watched this guy lie about EVERYTHING else, well, it just seemed he probably lied about his background too. He is a fraud and he's going through a lot of hassle and expense to keep everyone from finding out the truth.
