This is completely false.
Stick to the facts.
Actually it's not true or false. It's never been determined if someone born of a foreign national parent, but in the US, is "natural born". The only time the question arises is in eligibility for the Office of President. The only President known to have fit that description, other than BHO, was Chester Arthur, and his situation was not completely known until well after he left office. His father was not a citizen at the time of his birth, although, unlike BHO's father, he became one later.
