Read what you replied to again. It says that Trump's mother was a citizen of the US when Trump was born.
The test for NBC is the citizenship of the child's parents when the child is born, not the citizenship of the child's parents when the parents were born.
I agree. I was responding to what he wrote which was (in part) “No Foreign Parents” Yes Trump’s mother was Naturalized but she was still a foreigner as she was born in another country.
Again, My understanding of Natural Born Citizen is: A person who is considered a citizen at birth is a Natural Born Citizen. This would include Trump, Rubio and Ted Cruz. I also understand no matter what I say won’t change the mind of Trump supporters about this fact.
