Mike Catanzaro, the top White House staffer on domestic energy and environmental policy, will step down and return to the private sector next week as a consultant and adviser and CGCN Group. Francis Brooke, who currently works in Vice President Mike Pence's office, will replace Catanzaro on April 30.

Why it matters, from Axios' Amy Harder: Catanzaro was the adviser behind President Trump's top energy priorities, including repealing regulations and ethanol mandate reform. His departure will leave a vacuum of policy guidance even greater than that of George David Banks, his counterpart on international energy issues who resigned.
