Pruitt tried to lead Trump's assault on environmental policy and climate science, but even there he had a shaky record and ethics scandals kept piling up.

The EPA has taken at least 15 major actions on air pollution since Pruitt took over the agency—all opposed by leading public health groups.

Any crimp in solar’s growth could also forestall the kind of rapid clean energy transition that climate science says is urgently needed.
