The United States Postal Service is removing mail sorting machines from facilities around the country without any official explanation or reason given, Motherboard has learned through interviews with postal workers and union officials. In many cases, these are the same machines that would be tasked with sorting ballots, calling into question promises made by Postmaster General Louis DeJoy that the USPS has “ample capacity” to handle the predicted surge in mail-in ballots.

Motherboard identified 19 mail sorting machines from five processing facilities across the U.S. that either have already been removed or are scheduled to be in the near future. But the Postal Service operates hundreds of distribution facilities around the country, so it is not clear precisely how many machines are getting removed and for what purpose.

Even to local union officials, USPS has not announced any policy, explained why they are doing this, what will happen to the machines and the workers who use them. Nor has management provided a rationale for dismantling and removing the machines from the facility rather than merely not operating them when they’re not needed.
