If Pruitt exits, he will have served the shortest term of any EPA administrator in history, and will be the first forced out since Anne Gorsuch Burford, President Ronald Reagan’s first EPA administrator, resigned in disgrace in 1983. Burford was EPA’s first female administrator (not to mention the mother of Supreme Court Justice Neil Gorsuch), and stepped down after being cited for contempt of Congress for refusing to turn over Superfund records.

Pruitt’s aggressive attempts to roll back environmental regulations, undermine critical work on climate change and disqualify huge swathes of scientific research in favor of industry-backed science have defined his 14 months at the agency. Yet his future in the Trump administration now hinges on an ongoing White House review of his spending, his use of loopholes to give political appointees unapproved raises, and links to lobbyists who gave him a great deal on a Capitol Hill rental.
