For more than three months, the Trump administration tried to get climate science denier Kathleen Hartnett White confirmed for a top environmental post in the White House. But last week, the administration officially withdrew its nomination of Hartnett White, a clearly unqualified candidate who could have had dangerous implications for environmental and public health.

Trump was so committed to Hartnett White that he renominated her after the Senate failed to act on her nomination the first time. But in the end he couldn’t get this climate denier confirmed as the new chair of the White House Council on Environmental Quality, which coordinates environmental policy across federal agencies.

Who is Kathleen Hartnett White and why did she represent such a danger?
