From Newsmax:
Ken Burns, creator of the 1990 TV documentary miniseries on the Civil War, declared slavery alone caused the war – refuting chief of staff John Kelly's assertion a "lack of an ability to compromise" led to the conflict.
Many factors contributed to the Civil War. One caused it: slavery.
The White House chief of staff's comments Monday created a firestorm of criticism from historians, and a scorching denunciation from the Congressional Black Caucus, which said Kelly "needs a history lesson."
White House press secretary Sarah Huckabee Sanders, however, defended the remarks Tuesday.
"I do know that many historians, including Shelby Foote in Ken Burns' famous Civil War documentary, agreed a failure to compromise was a cause of the Civil War," she said, The Hill reported.
