David Barton opposes separation of church and state: Barton authored The Myth of Separation, arguing that "separation of church and state" was the exact opposite of what America's founding fathers sought. He hosts a nationally syndicated radio program, where he falsely claims that all of America's founding fathers were Christians, that the U.S. Constitution was written in accordance with Biblical principles with portions lifted "verbatim" from Scripture, and that Thomas Jefferson was basically a fundamentalist Christian, "way out there even further than most Religious Right today would be."
Most of Barton's books have been self-published by WallBuilders, an organization founded by Barton himself, but his 2012 book The Jefferson Lies: Exposing the Myths You've Always Believed about Thomas Jefferson, was published by a more established book company, Thomas Nelson. After numerous claims in The Jefferson Lies were debunked in mainstream media, Thomas Nelson conducted its own investigation, and then took the extraordinary step of withdrawing the book from distribution, even as its sales were strong. The company's press release stated, "... as we got into [the investigation], our conclusion was that the criticisms were correct. There were historical details — matters of fact, not matters of opinion, that were not supported at all." Glenn Beck tried, but failed, to defend Barton's The Jefferson Lies.
Barton has stated that America's slavery era was wrong not because owning humans is inherently vile, but because American-style slavery was not technically in keeping with Biblical slavery as described in the Old Testament books of Exodus, Deuteronomy, and Leviticus. He has wrongly written that the U.S. Congress funded publication of the first English-language Bible published in America, and that most signers of the Declaration of Independence held Bible College degrees (only one actually did). He also believes that Sunday sessions of Congress are inherently unconstitutional.
Barton often meets with and is referenced by prominent Republican politicians including Congresswoman Michele Bachmann (R-Minnesota) and Governors Sam Brownback (R-Kansas) and Mike Huckabee (R-Arkansas). Frequently billed at speaking engagements as "Dr. David Barton" and described as a historian, he holds a Bachelors' degree in Religious Education from Oral Roberts University, and an honorary doctorate from Pensacola Christian College. He served on the Texas State Board of Education's "panel of experts" that edited public school history textbooks to be more friendly to right-wing perspectives. Barton was one of Time magazine's 25 Most Influential Evangelicals in America (7 February 2005 issue).
