The White House will withdraw the nomination of Kathleen Hartnett White, the former Texas environmental official tapped to lead the Council on Environmental Quality, a White House official said Sunday.

The Washington Post first reported the planned withdrawal on Saturday.

Her nomination had been seen as troubled in recent days. Democrats and some Midwestern Republicans worried Hartnett White’s previous comments calling the EPA’s Renewable Fuel Standard unethical would lead to a weaker biofuels program.

Her nomination was advanced by the Senate Environment and Public Works Committee on a party-line vote in November, but she was unable to gain enough Republican support for a floor vote.

Environment and Public Works Chairman John Barrasso of Wyoming, who has praised Hartnett White as having “broad” experience in environmental issues, did not immediately respond to a request for comment. She is a former member and commissioner of the Texas Commission on Environmental Quality. The White House council coordinates federal environmental policy and actions among agencies and with states.
