The answer is: O’Reilly doesn’t have all the facts= he’s just talking off the top of his head...again.
Just like when he said he investigated the birth in Hawaii thing. First he said his investigation showed that 0 was born in Hawaii based on the newspaper announcement, but that was debunked, so now he says that he personally saw the BC and it is all in order, even though no one else has seen it. He’s so full of it.
