First and foremost, Natural Born status is a constitutional test that was established when the Constitution was written. It required both parents to be Citizens (Naturalized is fine) and the individual to be Born in the US. (Except for persons who were simply Citizens on the date of the adoption of the Constitution. - Which BO doesn't qualify)

Then you should have no problems pointing out what article of the Constitution that constitutional test is in.

In think here, there is no proof of his NBC status, in fact, he has stated that he was born a dual citizen which, to my mind, makes his birth divided and disqualifies him.

A person should be born NBC with no attachments from any country.
