US citizen, if born in Hawaii, but still not a “Natural-born” citizen.
If born in Kenya, then No, he would not be a US citizen at birth.
If they were married, then he’s not a “natural-born citizen” due to dual citizenship.
Either way you slice it, he still comes up empty.
But, the place of birth is irrelevant to the felony document fraud.
Indeed. But is Fraud a high crime or misdomeaner. Clearly if he was a Republican, it would rise to that level. But he's a 'Rat, with the 'Rats in control of Congress. He'd never even be impeached, let alone convicted and removed.
If born in Kenya, then No, he would not be a US citizen at birth.
If born outside the US, to an unwed mother, then under the law, he'd be a citizen at birth. The residence requirement for a US parent only applies to married parents. For bastards, the mother only need be a citizen of the US. But that's for "citizen at birth. Not necessarily "natural born".
But he didn't forge the CoLB out of embarassment that his parents were not married. Heck that would have given him more street cred in some circles, and more sympathy in others. It's only worth the effort, and the risk, if a real CoLB, or the Long Form Certificate of Live Birth indicates an ineligibility. IMHO only of course.
