The statement about Frederick Douglass was both historically and syntactically correct.
George Will has outed himself as a WhINO.
If Will's quotation is accurate, no.
The quote is, “Frederick Douglass is an example of somebody who’s done an amazing job and is getting recognized more and more, I notice.”
The error is, "who's done". It should be, "who did". Because the doer (1818-1895) is long gone and isn't going to be doing anymore.
Present perfect tense ("has done") vs simple past tense ("did").
