The Postal Service continues to add new leadership to its top ranks. The Senate confirmed Donald Lee Moak and Bill Zollars to serve on the Postal Service’s Board of Governors. They will restore the quorum the board lost earlier this month when Deputy Postmaster General Ron Stroman stepped down. Both are new to the agency. Moak served as president of the Air Line Pilots Association, and Zollars is the former chairman of the logistics company YRC Worldwide. Last week logistics executive Louis DeJoy took over as postmaster general.
