His Mother is/was an American citizen. Therefore he is an American

And, since his grandmother was the only one, to my knowledge, to make
any sort of statement which would call his citizenship into question,
and further, seeing how she died so shortly after his visit to her, I
would think only the amount of logic necessary to draw his citizenship
to scrutiny need be applied to argue a nice conspiracy theory here!
Yanno', the coincidence of her dying and eliminating the only eyewitness
