As you very well know, that has already been proven and ironically by the imposter himself when he publicly announced to the world that he’s not a natural born citizen but rather a native citizen with allegiances and loyalties to the foreign governments of Great Britain and Kenya.
Except that your definition of natural-born citizen is not supported by the Constitution, federal law, or any Supreme Court decision. It is an opinion of what natural-born citizen means, and nothing else.
