The founders did not place a definition in the USC for high crimes and misdemeanors either, but that has not stopped us from impeaching govt officials. that definition was derived from the British legal commentator Blackstone’s Commentaries on the Laws of England.
The definition of NBC was clearly derived from Swiss Jurist’s Emmerich De Vattel’s Law of Nations, To wit:
“The natives, or natural-born citizens, are those born in the country, of parents who are citizens. As the society can not exist and perpetuate itself otherwise than by the children of the citizens, those children naturally follow the condition of their fathers, and succeed to all their rights. The society is supposed to desire this, in consequence of what it owes to its own preservation; and it is presumed, as a matter of course, that each citizen, on entering into society, reserves to his children the right of becoming members of it. THE COUNTRY OF THE FATHERS IS THEREFORE THAT OF THE CHILDREN.”
