Two new members of the US Postal Service’s Board of Governors slammed the agency for its plan to slow delivery of first-class mail.

Ronald Stroman, one of President Biden’s three new appointees to the board, called the plan “strategically ill-conceived” Friday, according to a report.

Another new member, Anton Hajjar, worried about a proposed plan to end air mail delivery, saying that potential savings were not “quantified.”

Stroman, a former deputy Postmaster General, said at the board of governors’ meeting that the country was only now beginning to emerge from a global pandemic and that first-class mail delivery was far below pre-pandemic levels.

The changes, he added, “disproportionally impact our seniors, middle- and low-income Americans, [and] small businesses, who are our most loyal customers and most dependent on us.”

Postmaster General Louis DeJoy announced his 10-year plan to restructure the Postal Service in March. The cost-cutting plan calls for streamlining operations and reducing the reliance on air service to deliver the mail.
