The resignation of Environmental Protection Agency Administrator Scott Pruitt Thursday elicited cheers and pithy one-word statements from Democrats, who have been calling for Pruitt’s resignation for months as his ethics scandals have piled up.

During his short tenure, Pruitt drastically reshaped the EPA, shrinking its budget, rolling back Obama-era climate and environmental regulations, and giving outsize influence to industry over the agency’s agenda. Pruitt’s extensive list of potential ethical violations includes a $43,000 secure phone booth that the EPA purchased for his use, his travel spending, his housing and relationships with lobbyists, and his use of agency aides for personal business.
