The Topeka Capital-Journal reports that David Barton will speak at the gathering scheduled for March 27 in Topeka. Barton is founder of the Texas-based WallBuilders organization, an evangelical Christian group that supports a biblical view of U.S. history.
Last year, the publisher Thomas Nelson withdrew Barton's book, "The Jefferson Lies," citing historical errors. The book challenged the belief that Jefferson was largely secular and promoted the separation of church and state.
At his presentation at this month's Kansas Prayer Breakfast, Barton plans to speak on the history of prayer as practiced by early U.S. leaders.
