Top Congressional Democrats said on Thursday that the postmaster general confirmed in a closed-door meeting this week that he had instituted operational changes, and are urging him to change course amid reports of delays. 

House Speaker Nancy Pelosi (D-Calif.) and Senate Minority Leader Charles Schumer (D-N.Y.) noted in a letter to Postmaster General Louis DeJoy that he confirmed during a meeting with them that “the Postal Service recently instituted operational changes shortly after you assumed the position of Postmaster General.”

“These changes include reductions of overtime availability, restrictions on extra mail transportation trips, testing of new mail sorting and delivery policies at hundreds of Post Offices, and the reduction of the number and use of processing equipment at mail processing plants,” they added.

The letter comes after Pelosi, Schumer, White House chief of staff Mark Meadows and Treasury Secretary Steven Mnuchin met with DelJoy on Wednesday as part of their negotiations over a fifth coronavirus deal. Democrats want more money for USPS over concerns that they will be swamped by a spike of absentee ballots in November.

Schumer and Pelosi are urging DeJoy to reverse the changes, arguing that they undermine the timely delivery of things like mail, medicine and absentee ballots.

“In this moment, Americans have turned to the Postal Service and depend on it for the timely delivery of critical goods and a safe alternative to in-person interactions. As a result, we believe these changes must be reversed,” they added.

The two Democratic lawmakers also want an analysis on the impact of the recent changes, including how it effects delivery time and serviced.

David Partenheimer, a spokesman for the Postal Service, confirmed that they had received the letter but said they would be responding directly to Democrats. Partenheimer separately denied to the Associated Press USPS is slowing down deliveries.

"We continue to employ a robust and proven process to ensure proper handling of all election mail consistent with our standards,″ he told the AP.

 In addition to the letter from the two top Democrats, Sen. Gary Peters (D-Mich.), the top Democrat on the Homeland Security and Governmental Affairs Committee, announced on Thursday that he was starting an investigation into delivery delays.
