Maybe you could provide a little more info, and I am not saying this in a challenging manner. I don't want to read something as fact if it is invented! If this Barton is a fabricator, maybe post some evidence.
Sure, how about
a page from his own website, recanting several supposed "quotes" from the Founding Fathers concerning their views on the role of religion in America. Barton has for years repeated these "quotes" authoritatively, but now admits are either false or unable to be verified.
While the explanation on Barton's website seems to paint these misquotes as innocuous or accidental historical inaccuracies, other religious and historical authorities have stated their belief that Barton knowingly fabricated these misquotes never expecting to have them so scrutinized and exposed.
