If it was his newsletter with his name and reputation associated with it, as it appears to have been, he was either extremely foolish and irresponsible... or... he agreed with what was written in it. In either case, he isn’t off the hook.
Well, he’s been off the hook with his voters, who are 1/8th Black and 1/8th Hispanic. Nobody cares down there. His story that he fired the man is accepted.
I would be glad for him to get national media coverage to answer the question.
