You can't prove that. The babydaddy might have been Frank Davis, who was a citizen. Except BHO can't go there now because Bill Ayres forged a history for him in a best selling fiction. Ironic.
Those pesky divorce papers on file in Hawaii between his mother and his Kenyan father is all the proof that is needed --
I have more proof that he is, than I have that he isn’t
* Obams’s own statement in 2 books he wrote
* Every birth certificate says he is...
* Every family member says he is.
* Divorce decree says he is...
* Adoption proceedings for Lolo Soetoro says he is...
* Family in Kenya, and the US say he is, and have pictures..
What do you got?? Conspiracy theories for Frank Marshall Davis, or Rape stories???
Give me facts and evidence that verify anything...Hey, we could get DNA from Obama, and Davis, and Malcom X? LOL
Whatayagot??
