The Senate has confirmed fracking executive Chris Wright as secretary of energy. Wright has long advocated for fossil fuels and has publicly denied the existence of the climate crisis. He’s the founder of the Denver-based oil field firm Liberty Energy, and until recently served on the board of Oklo, a nuclear power startup.

Wright’s confirmation came as the Trump administration sent emails to over 1,100 recently hired Environmental Protection Agency workers, warning them they could be fired at any time. The New York Times reports the affected staffers work on climate change, air pollution reduction, clean energy and enforcing environmental laws like lead pipe remediation.
