On August 21st, Secretary Alexander Acosta appointed his former chief of staff, Capitol Hill veteran Wayne Palmer, as acting Assistant Secretary of Mine Safety and Health. Palmer’s replacement at the Department of Labor, Nicholas Geale (who is also the Department’s acting Solicitor), stated that Palmer is from Pennsylvania and has “mining in his family’s background.” Palmer’s political experience includes working for Senators Rick Santorum (R-PA) and George Voinovich (R-OH), as well as lobbyist for the pharmaceutical industry.

Department of Labor spokesman Eric Holland said Acosta "is confident that Mr. Palmer's abilities and government experience will complement the eventual nominee's deep industry expertise. In the meantime, Mr. Palmer will collaborate with senior career staff, who bring decades of experience to the table, on immediate priorities to improve the safety and health conditions for all American miners."

He is the past chairman of the Ohio Coal Association and a member of Mine Rescue Veterans of Pittsburgh.Several insiders have noted that the confirmation process for Mr. Zatezalo could take months to complete.
