Except that is not what the are implying on their website :
In June, the Obama campaign released a digitally scanned image of his birth certificate to quell speculative charges that he might not be a natural-born citizen. But the image prompted more blog-based skepticism about the document's authenticity. And recently, author Jerome Corsi, whose book attacks Obama, said in a TV interview that the birth certificate the campaign has is "fake."
We beg to differ. FactCheck.org staffers have now seen, touched, examined and photographed the original birth certificate.
By saying they "beg to differ" they are impying that the document they "examined" is the same one put up on the Kos site.
But they only examined what they examined. I don't think they would know how the one got to Kos and if it was the same.
