“At the time the Constitution was written, a foreign national woman marrying a US citizen husband automatically became a US citizen. But that changed.”
The regular laws that changed the status of foreign born wives are not Constitutional Amendments and should not alter the rules in the Constitution.
As an Originalist I argue that Don Jr. is Natural Born for Constitutional purposes because he was born to an American father on American soil.
It’s a very debated topic and ultimately SCOTUS may rule on it.
