Nothing about the word "natural" demands something about the citizenship status of one's parents.
That is not what the phrase means. If she was born in the US then her parents have nothing to do with it.
‘Natural’ means that nobody but parents can bequeath. NO function of any part of government can give or take ‘natural born’ US citizenship ... The founding fathers ... ‘we the people’ are government .... IF her parents were not US citizens, they have absolutely NO power or authority to bequeath to their child ‘natural born’... US citizenship . She is at best an anchor baby... IF that.
I know, I was taught long before the many decided they would pervert the US Constitution ... how I know ... My two US citizen parents, birthed me in Germany ... I have NO US state birth certificate ... I have a State Department document giving me citizenship, signed (auto penned ) by Dean Rusk.
