For most people, the last day on the job before retiring is a celebration. But Michael Cox capped off his career at the Environmental Protection Agency (EPA) with a scathing letter to agency head Scott Pruitt.
Since 1987, Cox has worked for the EPA. Most recently he served as climate advisor for Region 10 — which covers Alaska, Washington, Oregon and Idaho.
He was planning on retiring — but not like this. He says he wants the agency to be successful.
