His reasoning(besides the fact that he doesn't believe in climate change being caused by humans) is that he wants to bring on board folks "with more diverse views". Like his I expect since scientists are locked in to FACTS and FACTS annoy the he** outta Pruitt. They don't match his beliefs. So be prepared for non-science folks who will quite likely have ties to the fossil fuel industry. They would be as anti-science a group as any since their dog is in that fight isn't it? But we know that is precisely why The Donald John put Scott Pruitt in charge. The attitude of Trumpworld and its denizens is that anything science-based is VERY BAD. Anything education based is VERY BAD. Anything fact-based is VERY BAD. They try their dam*dest to avoid VERY BAD.
