In Pruitt's place, the president is appointing EPA Deputy Administrator Andrew Wheeler, who is poised to pick up where Pruitt left off.
Yet for many critics, who have watched with apprehension as Wheeler ascended the EPA ladder, that kind of experience and approach is beside the point.
"Within the Agency Scott has done an outstanding job, and I will always be thankful to him for this", added Trump. In an interview Thursday with Elaine Quijano on CBSN's "Red & Blue" after his resignation, Mink said she's "glad he took the hint".
Pruitt, who faced 14 investigations into his ethics and practices while at the EPA, resigned Thursday as head of the agency. Wheeler was serving as a lobbyist for Murray Energy at the time. "We've gotten rid of record breaking regulations and it's been really".
"Wheeler is much smarter and will try to keep his efforts under the radar in implementing Trump's destructive agenda", Jeremy Symons, vice president for political affairs at the Environmental Defense Fund told Politico in May of this year.
He's been investigated for undertaking expensive, first-class worldwide travel with a large detail, and for spending $43,000 to build a soundproof phone booth in his office. He also demanded 24-hour-a-day protection from armed officers, resulting in a swollen 20-member security detail that blew through overtime budgets and racked up expenses of more than $3 million. He had also enlisted his staff to contact conservative groups and companies to find a lucrative job for his unemployed wife, including emails seeking a Chick-fil-A franchise from a senior executive at the fast-food chain.
On top of that, he entered into, for example, a controversial rental arrangement for the first six months of his tenure, with the wife of a lobbyist, herself a lobbyist on Capitol Hill, where he only paid $50 a night on the nights that he stayed there.
The rollback was immediately condemned by environmental groups, which have appealed to the White House to block the EPA from creating the loophole.
It was not immediately clear how Pruitt's resignation might affect those ongoing probes.
"Scott Pruitt's reign of venality is finally over".
"We see Mr. Wheeler as fitting a very typical pattern of behavior", said Chris Saeger, of the Western Values Project.
When Pruitt sued the EPA 14 times as Oklahoma attorney general between 2011 and 2017 on behalf of polluting industries, a top petitioner and co-petitioner in half those cases was coal giant Murray Energy. "The EPA should be working with NY - and not against us - to address climate change, protect our water resources and ensure the health of our residents". "And I think Scott felt that he was a distraction".
Americans deserve an EPA administrator who they know, without a shadow of a doubt, has their best interests in mind.
"I have accepted the resignation of Scott Pruitt as the Administrator of the Environmental Protection Agency", tweeted the president, ending months of speculation about the future of the man he had tasked with dismantling former president Barack Obama's green legacy.
