Iowa Congressman Bruce Braley found a factual error in Ken Burns’ The War, reports Radio Iowa. In his description of “one of the most famous Iowa families involved in that war,” Burns says the five Sullivan brothers were from Fredericksburg. ” ‘That came as a great surprise to all of us living in Waterloo, home of Sullivan Park and the Five Sullivan Brothers Convention Center,’ Braley says. Braley faxed a letter to Burns today, praising his work as a filmmaker but pointing out the error.”
