The Fourteenth Amendment framer, Rep. John A. Bingham, in 1871, gave a definition of Natural Born Citizen, which stated in part:
every human being born within the jurisdiction of the United States of parents not owing allegiance to any foreign sovereignty is, in the language of your Constitution itself, a natural born citizen.
So, to restate Rep. Bingham’s definition of “natural born” in 21st century terms:
1. Born on U.S. soil;
2. Parents are citizens at the time of birth.
I’m not making this stuff up, you know!
