CNN:

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

It also comes two days after an exclusive CNN investigation revealed a former top aide alleged Pruitt and his staffers held regular meetings to “scrub,” alter or remove controversial events from his calendar. That investigation sparked two Democratic congressman to call Thursday for the EPA inspector general to investigate whether Pruitt committed a federal crime.

It’s insane that Pruitt was able to hang on to that position for as long as he did.
