The theatre of the Absurd has reached New Heights. If you don't understand something, you shouldn't be running the department that focuses on it. The legislature should have vetted his expertise before even proposing him as a candidate.
In comparison this is just a minor issue.
What annoys me more is when specialists give governments expert advice and then the government still goes off and does the complete opposite because of some predefined agenda they had. Or worse still, because of coercion from lobbyists.
