You are incorrect, born in the USA with a US citizen father. Is how the founders would have defined natural born citizen, since a wife assumes the citizenship of her husband back in their day.
In other words no other citizenship but US at birth.
Gabbard has a stronger claim than Harris since American Samoa is a US territory. Should be interesting if anyone of note makes the argument that they are not NBC.
American Samoa was “unincorporated” when she was born. Samoans were uniquely US Nationals not citizens. However her mother was US citizen and that was an exception to National. Gab was a US citizen at birth.
I could not establish her father’s citizenship. He is said to be a US citizen when he served in congress from Hawaii. What he was when she was born, i do not know.
