I lamented the failure of journalistic exposes to dislodge EPA Administrator Scott Pruitt too soon this morning. The scandal-ridden Pruitt has resigned.

This much doesn’t change: The damage he’s done to the environment already.

From CNN:

Environmental Protection Agency Administrator Scott Pruitt has resigned after months of ethics controversies, President Donald Trump tweeted Thursday.

“I have accepted the resignation of Scott Pruitt as the Administrator of the Environmental Protection Agency,” Trump tweeted. “Within the Agency Scott has done an outstanding job, and I will always be thankful to him for this.”

Pruitt’s resignation follows months during which the EPA administrator has been embroiled in one ethics controversy after the next.

Trump said on Twitter that Pruitt’s recently-Senate confirmed deputy Andrew Wheeler will on Monday assume the duties of acting administrator of the EPA.

But again: Let’s not forget he came to the office and his ruinous performance with the highest praise from former Democratic Attorney General Dustin McDaniel and current Republican Attorney General Leslie Rutledge, who hosted Pruitt on a visit to Little Rock and cheered his every pollution-enabling move.
