What court has asked to see it? And even if some court somewhere down the line demands to see Obama's "vault" BC, they're going to have to take that request up with Hawaiian officials, not Obama.
An honest person, an honest president, who claims transparency would have at least have offered to show a court the same document that he showed "factcheck".org and the DailyKos as proof of being born in Hawaii.
But we all know Obama's not honest.
Yes, some court would subpoena for the source document for Obama's COLB if it goes to discovery. But that Obama COLB will never see the inside of a courthouse because it's forgery.
