"Leslie Beyer has left the department just months after she was confirmed by the Senate."

"The Interior Department confirmed Friday that Leslie Beyer, who has led the agency’s energy programs on public lands and waters since her Senate confirmation in September, has left the agency.

Beyer served as assistant secretary for land and minerals management, one of Interior’s most critical leadership positions. The role oversees all of Interior’s energy and mining offices, including the Bureau of Land Management and the Bureau of Ocean Energy Management.

The position will now be filled temporarily by Lanny Erdos, the department’s director of the Office of Surface Mining Reclamation and Enforcement."
