Yes we clearly need a USSC definition. They rejected 6 cases on Sotero.
Jay and Washington exchanged a letter expressing their concern about a “foreigner” being commander -in-chief.
We also have Vattel’s definition from 1744 which the founders knew about. A NBC has citizen parents and is born in country.
Here is the logic. If a child born in the US but has foreigners as parents, the child has a choice of citizenship. Using Sotero, his father was British as a Kenya at that time. So Sotero could have declared british or US. Does anyone think the founders would have accepted a Brit as commander in chief, especially after two wars?
The ability to have options about your citizenship means you are not automatically a NBC; thus you are ineligible to be president.
This recently applied to Jindal, Harris, Sotero, and I don’t know about Vivek’s parents.
There is also the question of his mothers citizenship. At the time she appears to have lacked the required residency in the US to automatically bestow citizenship on her child.
