The thing is, none of this would affect his original birth certificate, the one issued when he was born, IF he was actually born in Hawaii. From what some of his own relatives have said, I believe he was born in Kenya.
Au contraire, mon frere. A registered adoption means the original birth certificate is sealed, and a new one issued with the adoptive parents shown. This is the real reason he won’t release his birth certificate. He is not using his real name, Barry Soetero.
