When news of the old report surfaced last year, Donald Trump vehemently denied his father's arrest. "He was never arrested. He has nothing to do with this. This never happened. This is nonsense and it never happened," he said to the Daily Mail. "This never happened. Never took place. He was never arrested, never convicted, never even charged. It's a completely false, ridiculous story. He was never there! It never happened. Never took place."

It's worth noting that Trump's comments came one day after another Klan brawl, this time in Anaheim, Calif. Thirteen people were arrested and three were stabbed after a Klan rally turned violent. And it's worth noting, too, as did Jonathan Chait at New York magazine, that Trump's claim to "know nothing" about white supremacists echoes the language of the 19th-century "Know Nothing" party — a nativist group that supported only Protestants for public office.
