Kathleen Hartnett White was announced last October as Trump's choice to chair the Council on Environmental Quality.
But White's nomination languished and was among a batch of nominations the Senate sent back to the White House when it adjourned at the end of 2017.
Trump returned White's nomination to the Senate in January.
The Washington Post first reported late Saturday on the plans to pull White's nomination, citing two unnamed administration officials who had been briefed on the matter.
