Two of embattled EPA chief Scott Pruitt’s top aides have resigned, the agency said Wednesday.

Millan Hupp resigned just days after her testimony to a Congressional committee was revealed by lawmakers, The Atlantic magazine reported, saying her last day would be Friday.

Sarah Greenwalt, a senior counselor to Pruitt, also resigned on Wednesday, the Washington Post reported. Her resignation is set to take effect early next week.

It was revealed on Monday that Hupp had performed a series of personal errands for her boss on the taxpayers’ dime — including trying to buy a used mattress from President Trump’s DC hotel.

Hupp, Pruitt’s scheduler, helped him land a below-market rate room in a lobbyist’s condo, booked him a Rose Bowl trip so he could see his home state Oklahoma Sooners play and tried to score the “Trump Home Luxury Plush Euro Pillow Top” mattress.

One top EPA official said that Hupp, 26, was “tired of being thrown under the bus by Pruitt,” who maintains the support of President Trump despite myriad scandals at the agency that have sparked roughly a dozen federal investigations.

Democratic lawmakers called the errands a violation of federal law that prevents federal employees from doing personal favors for their bosses on work time.

Reached by phone, Jahan Wilcox, an EPA spokesperson, would not comment but told Atlantic reporter Elaina Plott: “You have a great day, you’re a piece of trash.”

Hupp and Greenwalt — who both came to DC with Pruitt from Oklahoma — were the two aides whom Pruitt wanted to award fat raises before he was blocked by the White House.

Pruitt, who had another staffer try to arrange for his wife to get a Chick-fil-A franchise, later claimed he was unaware of the raises.
