The only one that I know of, for sure, that has stated that they’ve seen the birth certificate is the State of Hawaii, through their official website...

“I, Dr. Chiyome Fukino, Director of the Hawai‘i State Department of Health, have seen the original vital records maintained on file by the Hawai‘i State Department of Health verifying Barack Hussein Obama was born in Hawai‘i and is a natural-born American citizen. I have nothing further to add to this statement or my original statement issued in October 2008 over eight months ago.”
And since the State of Hawaii is an official government organization, plus a “state” and the *very state* that holds the birth certificate, and from the beginning, and they are the only ones who can even issue a “certified copy” — I would say that this is pretty solid and definitive — when they say that Obama was born in Hawaii and that Obama is a natural-born American citizen.
BUT..., if you really want to *see* the birth certificate for yourself, the only way that’s going to happen is if you get a state law passed to that effect...
O’Reilly made the claim that he investigated, saw the document, and it’s all hogwash and we are all cranks
