The President Donald Trump tweeted the news Thursday, praising Pruitt’s performance at the EPA and confirming that deputy administrator Andrew Wheeler would take over the helm as acting administrator.
The departure follows months of scrutiny that gathered momentum following reports that Pruitt had rented a Capitol Hill condominium linked to an energy lobbyist on favorable terms. The revelation exacerbated concerns about the high cost of Pruitt's travel and security detail and triggered a flood of allegations that Pruitt fostered a culture of workplace retaliation, wasteful spending and self-dealing at EPA.
The steady flow of negative news stories prompted multiple government investigators to open several inquiries into Pruitt. His EPA now faces about a dozen probes into its spending, ethics and policy decisions.
