David E. Williams, formerly chief operating officer and executive vice president, will take the role of chief logistics and processing operations officer, a new position for a trusted adviser to former postmaster general Megan Brennan and members of the agency’s governing board. A new organizational chart also gives Williams the title “executive vice president,” though that role was not included in the internal restructuring announcement obtained by The Washington Post. The Postal Service’s Kevin L. McAdams, the vice president of delivery and retail operations and a 40-year USPS veteran, was not listed on the chart.
