EPA staffers often convened in Pruitt's office to nix numerous records from the agency chief's calendar to cover up a paper trail, Kevin Chmielewski, a former deputy chief of staff for operations at the EPA. In his resignation letter he said, "The unrelenting attacks on me personally, my family, are unprecedented and have taken a sizable toll on all of us".
Pruitt has faced an array of ethical questions about his travel spending, security costs, dealings with industry lobbyists and misuse of government resources.
Pruitt remained silent while Mink spoke, according to the cellphone video shot by Mink's husband. Nothing happened with that because Pruitt does the will of giant fossil fuel companies, which greatly pleases the people of West Virginia, which greatly pleases the president.
The allegations and investigations came as Pruitt appeared to be using his job in the Trump administration to position himself for an eventual run at political office, perhaps as senator or governor in Oklahoma with an eventual eye on the presidency.
"We deserve somebody at the EPA who actually does protect our environment", Mink continued.
The story comes at a time when Pruitt is embroiled in several investigations and Sessions has been the butt of criticism from Trump over his recusal from the Russian Federation investigation.
Mink told ABC News that she felt compelled to speak up, in part, because Pruitt's push for corporate deregulation felt "personal". Many of the EPA regulations Pruitt scraped or delayed had not yet taken effect, and the tens of thousands of lost coal mining jobs the president pledged to bring back never materialized.
Wheeler is expected to serve in an acting capacity as head of the EPA until Trump nominates a new agency chief, who must then be confirmed by the Senate. The Washington Post reports top Pruitt aides have detailed further questionable spending and management decisions to congressional investigators.
When we last surveyed the mess of scandals trailing the man in charge of upholding this country's environmental standards, we talked about the millions of taxpayer dollars he spends on a security detail, his sweetheart condo deal, and his $40,000 phone booth. The anecdotes offered ammunition for critics of the now-outgoing EPA chief as a creature of the swamp Trump promised to drain.
