We don't know - most likely a foreign passport from indonesia.
based on what? So let me get this right. Obama was born in Kenya, flew to hawaii, then to indonesia on a fake indonesian passport. Then flew back to the US on a fake indonesian passport, then got a fake birth cert and fake ss numbers, then became friends with a terrorist and asked him to write his book, then became president and now has the state of hawaii lying for him to prove all this is false?
Wow. Dude you are fu*ked in the head hahaha
