Sonderling has led the department in an acting capacity since Lori Chavez-DeRemer stepped down in April and now requires Senate confirmation for the permanent post.
President Trump said Monday he will nominate Keith Sonderling to serve as labor secretary, moving to install the acting department head in the job permanently. Sonderling has been running the agency since Lori Chavez-DeRemer resigned in April after a tumultuous tenure. The nomination now goes to the Senate, where he must win confirmation to take the role on a permanent basis.
