“This conspiracy theory is the most far-flung thing I think I’ve ever heard,” says Stephen Kearney, who worked at the USPS for 33 years, including as treasurer and a senior vice president. “DeJoy was not appointed by President Trump,” but by the USPS’s bipartisan governors. (Who, as it happens, selected him unanimously.)

“You can find valid operational reasons for the actions taken by the Postal Service so far,” says Mike Plunkett, another longtime USPS executive who now leads the Association for Postal Commerce. “In no way do I detect any criminality behind them, and I’m at a loss as to how one would reach that conclusion.”…

Mr. Kearney, who now runs the Alliance of Nonprofit Mailers, concurs. “It’s obvious, to be efficient and not waste money, you need to take out some of that capacity,” he says. His group has similarly been urging productivity improvements, “because if they don’t do that, our postage rates are going to go way up.” A leaked USPS document floating in the online ether is titled “Equipment Reduction.” But it’s dated May 15, and Mr. DeJoy took over June 15.
