To be fair, I think it holds true for any head of department of health (or whatever they're called) - that's a position that calls for organizational skills and not a medical doctorate. In the same way my project manager doesn't answer questions about clustered datastorage, that's what he has people like me for.
However, leading JFKJrs department also calls for common sense and skepticism towards conspiracy theories, two qualities he severely lacks. But at least he's right in that particular statement.
