Now I know what the laws of Kenya are regarding duel citizenship, where is the proof of whatever action the bamster took?
Even if he did, he was still born with divided loyalties per OUR Constitution. He's not a NBC.
From MINOR v. HAPPERSETT, 88 U.S. 162 (1874)
...all children born in a country of parents who were its citizens became themselves, upon their birth, citizens also. These were natives, or natural-born citizens
Which parrallels very closely the language in Vattel's "Law of Nations" section 212
The natives, or natural-born citizens, are those born in the country, of parents who are citizens
