Scott Pruitt, the most malignant Environmental Protection Agency chief ever, has resigned. EPA deputy Andrew Wheeler, almost certainly another anti-environmentalist, will take over in the interim. Pruitt impressed many in the media as the dirtiest, swampiest cabinet chief in government history, his actions having reportedly inspired 14 separate investigations. (Here’s a list of 13.) Pruitt, 50, had been very popular among conservatives for his absolute indifference to the health of the planet, but his ethical scandals were overwhelming.

From N.Y. Times: “Pruitt began the largest regulatory rollback in the EPA’s history, undoing, delaying or blocking several Obama-era environmental rules…among them was a suite of historic regulations aimed at mitigating global warming pollution from the United States’ vehicles and power plants.”
