According to sources, Don Jr was born in NY. Is NY not a part of the US anymore?
To a mother who was not a US citizen from whom he inherited foreign nationality.
Natural born citizen are NATURALLY citizens because they CANNOT be anything else.
Anyone born with more than ONE nationality is NOT a natural born citizen.
It was that singularity of nationality that the founders were requiring.
John Jay to George Washington:
“Permit me to hint, whether it would be wise and seasonable to provide a strong check to the admission of Foreigners into the administration of our national Government; and to declare expressly that the Command in Chief of the American army shall not be given to nor devolve on, any but a natural born Citizen.”
NYC is debatable.
