David Barton, born January 28, 1954, is a Christian evangelical minister, historian, political activist, and author known for promoting controversial claims that the United States was founded as a Christian nation. He is the founder of WallBuilders, LLC, a Texas-based organization established nearly four decades ago that advocates for America's "Christian heritage" and asserts that the separation of church and state is a myth. Barton has authored numerous best-selling books on American history and is a sought-after speaker at churches, civic groups, schools, and universities. He has served in political roles including consultant to the Republican National Committee and vice chairman of the Texas Republican Party. Barton is a close associate and frequent guest of Glenn Beck, collaborating extensively on historical content and appearing on Beck’s programs. His work has been described as Christian nationalist and criticized by groups such as the Texas Freedom Network as amateur historical propaganda. The Southern Poverty Law Center has condemned him for demonizing LGBTQ communities, including claims that HIV and AIDS are divine consequences of their lifestyles. Despite scrutiny for historical inaccuracies, Barton remains influential in conservative Christian and Republican circles, advising political figures like House Speaker Mike Johnson.
