This should prove interesting, Obama lost the court battle challenging his citizenship. He must provide the following:
a. certified copy of this Birth Certificate;
b. certified copy of his Certificate of Citizenship; and,
c. certified copy of his Oath of Allegiance.
Obama's lawyer, who also happens to be CAIR's lawyer, will probably appeal. Apparantely there are no provisions to force an individual who is Running for POTUS to prove he is a natural born citizen prior to running.
