The Government Accountability Office (GAO) is now investigating whether Acting Department of Labor (DOL) Secretary Julie Su has the legal authority to lead the agency. It is becoming increasingly clear that there are not yet the votes to confirm her as DOL Secretary. However, her nomination has not been withdrawn, nor is it scheduled for a Senate vote. Instead, the Administration is saying it has the authority to leave Su in place as Acting Secretary. This is triggering talk of a legal challenge to any actions taken by DOL during what some are calling Su’s illegal time as acting head of the agency.
