Scott Pruitt, perhaps the worst of all Donald Trump’s administration picks (and damn that’s saying a lot), made a mockery of the confirmation process and the job he’s applying for when he answered a Senate committee’s questions today.

Having already made part of his career willfully denying climate science, fighting to dismantle the agency he now wants to head, and turning a blind eye to the polluters the government seeks to “handicap” with, you know, red tape that prevents poisoning the air and water supply, today Pruitt added that his own opinions on climate science (he’s a denier) were immaterial. Which is one way of saying that the EPA might as well base enforcement decisions on randomly generated numbers — or campaign donations.

Verdict: a disaster waiting to happen.
