The federal environmental protection agency’s director is facing calls to step down over his role in the agency’s response to the crisis.
The Environmental Protection Agency announced late last month that Lisa Rosenberg would step down, with an appointment to her job in the U.S. Department of Justice.
She had been the agency, among other posts, since 2010.
The agency said Rosenberg has a long history of conflict of interest.
It also said she received millions in donations from the oil and gas industry and lobbied for fossil fuel companies during her time in government.
She has denied the allegations.
The appointment comes after the Trump administration issued a list of nine recommendations to rein in the EPA’s leadership, including eliminating the agency from the federal budget and cutting the agency budget by a third.
Rosenberg’s appointment came in the wake of a series of high-profile scandals involving the agency and its top leadership.
She has been under fire since President Donald Trump appointed her director in March.
She was appointed by President Barack Obama in 2009.
Her confirmation was quickly blocked by the Senate, where Republicans hold a 52-48 majority.
EPA Administrator Scott Pruitt is expected to win confirmation in the Senate next week.
