A known Donald Trump supporter (and former Trump campaign employee) is revealing some disturbing information about what it was like to work for EPA Administrator Scott Pruitt. Former EPA staffer Kevin Chmielewski was reportedly fired for questioning some of the shady things that Pruitt was doing. CNN reports:

“EPA Administrator Scott Pruitt and his aides have kept “secret” calendars and schedules to overtly hide controversial meetings or calls with industry representatives and others, according to a former EPA official who is expected to soon testify before Congress. A review of EPA documents by CNN found discrepancies between Pruitt’s official calendar and other records.

EPA staffers met routinely in Pruitt’s office to “scrub,” alter or remove from Pruitt’s official calendar numerous records because they might “look bad,” according to Kevin Chmielewski, Pruitt’s former deputy chief of staff for operations, who attended the meetings.”

Watch CNN’s exclusive interview with Chmielewski above and add this to the growing list of swampy things Pruitt has allegedly done while leading up the EPA. Just yesterday the Washington Post uncovered another couple of possible new ethics violations:

“Two of Scott Pruitt’s top aides provided fresh details to congressional investigators in recent days about some of his most controversial spending and management decisions, including his push to find a six-figure job for his wife at a politically connected group, enlist staffers in performing personal tasks and seek high-end travel despite aides’ objections.”
