2 of Scott Pruitt’s closest aides, also facing scrutiny, are leaving the EPA

Two of Scott Pruitt’s most trusted aides have given notice that they are leaving, as the Environmental Protection Agency chief faces growing scrutiny over his spending and management decisions, according to current and former agency officials who spoke on the condition of anonymity to discuss personnel moves.

Sarah Greenwalt, a senior counsel at the EPA who also worked with Pruitt when he was Oklahoma attorney general, had garnered attention for the 52% raise she received earlier this year, before the EPA reversed the decision.

The other departure, initially reported Wednesday by the Atlantic, is that of Millan Hupp, Pruitt’s top scheduling and advance official. She also worked with Pruitt in Oklahoma, helping with fund-raising under his political action committees.

Hupp, who at the EPA served as a gatekeeper, travel planner and confidante of the administrator, had drawn the attention of lawmakers on Capitol Hill recently for the personal tasks she also performed for Pruitt. Those included helping with his Washington housing hunt, booking his personal travel and even contacting the Trump hotel in search of a used mattress on his behalf.

The departures are the latest and possibly most significant in a line of political appointees who have left the agency. Top communications official Elizabeth Bowen left recently, as did former top advisor Samantha Dravis.

The EPA did not immediately respond to a request for comment.
