On Thursday afternoon, President Donald Trump tweeted that he was accepting the resignation of EPA head Scott Pruitt.

“I have accepted the resignation of Scott Pruitt as the Administrator of the Environmental Protection Agency. Within the Agency Scott has done an outstanding job, and I will always be thankful to him for this. The Senate confirmed Deputy at EPA, Andrew Wheeler, will…” the President tweeted. …on Monday assume duties as the acting Administrator of the EPA. I have no doubt that Andy will continue on with our great and lasting EPA agenda. We have made tremendous progress and the future of the EPA is very bright!”

Pruitt faced a number of corruption scandals during his brief tenure at the helm of the EPA, most recently over his use of secret calendars and schedules. He’s also been held to task for exorbitant spending of taxpayer money.
