Dinesh D’Souza covered the “Klanbake” in his documentary “Hillary’s America”. This is where I first learned about it. He features the photograph in question on the documentary website. (See evidence point #9 HERE).
Since the same photograph is sourced in numerous digital history archives, I used an alternative reference so liberal readers would not cry foul. Most liberals have been convinced by media propaganda that D’Souza is not a credible source. It is a shame that they are missing out on such a studied raconteur of American history.
