I’ve seen similar threads for the past several weeks.
Regardless of the citizenship status of whoever may or may not have been his biological father, his MOTHER was a US Citizen, and he therefore is a natural born citizen of the United States.
Well obviously I am not smart enough, nor do I have the energy to debate this particular topic with you but I will say this, if it was as cut and dry as you are making it sound no one would be questioning his citizenship. Many, many people on the right don’t see it the way you do.
