Not silence at all, his father was a Kenyan as far as I know. I have no reason to dispute that though it might be disputed that B.O. Sr is his actual father and perhaps that is the embarrassing information contained in his original birth certificate. If his father was, as some claim, Frank Davis, then the citizenship would not be in question.
Nonetheless, as far as I know, born in Hawaii to an American mother qualifies one for citizenship regardless of who the daddy is.
Ah yes, the axelgreasy talking point of conflating citizen with natural born citizen. Carry on, obamanoid.
And what about the other documents that he refuses to release? Is he above the law? This is about more than a birth certificate!
I'll say it again...This is the distraction within the "records" issue. The "birth certificate controversy" is the sacrificial pawn to keep attention away from the rest of the records that have never been released.
