Fascinating. The one that was most interesting is that even if he were born in Hawaii, he was the son of a Kenyan man, who was then a British citizen and so could not have been eligible to run for President.
He also was adopted into Indonesian citizenship. If he was a US citizen in order to keep it he would have to sign up for it by a certain age, which there isn’t any known record of. To become an Indonesian citizen other citizenships have to be striped.
