“I don’t recall him ever having objected to anything,” Mr. Barger said, “or I would have asked him why. And it would have been considered.” Mr. Williams is expected to testify on Thursday before lawmakers from the Congressional Progressive Caucus.
Mounting pressure prompted Mr. DeJoy to backpedal on many of his changes, saying post office hours would not be shortened, mail-processing equipment and mailboxes would remain, and overtime would continue to be approved, as needed. But state officials, postal workers and union representatives said some damage has already been done. Hundreds of sorting machines, union officials and workers said, have already been destroyed.
Since the changes were put in place, large institutional Postal Service customers have reported mass mailings routinely arriving at home addresses a day or two later than their intended delivery date, said Michael Plunkett, the president of the Association for Postal Commerce, or PostCom.
His group represents catalog makers, banks, phone companies and other businesses that produce and send large quantities of mail. He attributed the delivery delays to the cutting of overtime and truck trips between processing plants and post offices.
“It appears as if they made these changes without taking into account the effect that it might have on service,” he said.
More than 20 states announced Tuesday that they would sue the Trump administration over the changes, claiming that they were unlawful, disadvantaged residents and disenfranchised voters. Josh Shapiro, Pennsylvania’s attorney general, who plans to file a lawsuit on behalf of the state on Wednesday, said in an interview that Mr. DeJoy’s changes have caused delays for small businesses and veterans and people who receive their prescription medicines in the mail. In some cases, he said that medicines that require temperature control have taken three times as long as usual to arrive, potentially compromising their potency, and that the delays have been particularly problematic for veterans.
Mr. Shapiro said the state had found evidence of mail left in boxes and trucks because of cutbacks on overtime pay for postal workers. The lawsuit will claim that the changes are illegal because they did not go through the normal postal regulatory commission process and are undermining the right of Pennsylvanians to vote.
