To say that the Founding Fathers never defined what a Natural Born Citizen is, is a blatant lie.
Clearly they did and they wrote it into law with the very first Congress....
That trumps any translation of Vattel you want to talk about.
They defined by law what a Natural Born citizen is.
Cut and dry, a Natural Born Citizen is the offspring of TWO US CITIZENS.
And it doesn’t have to appear in the law that congress wrote after that under the Naturalization act.
Once Defined it takes a similar act of Congress written into law to redefine it.
Which by the way has been tried many time over the years with no success.
The fact that it was dropped from subsequent versions of the Naturalization act means nothing, nada, zip, zelch, zed.
It was defined once and it is that definition that stands even to this day.
