Postmaster General Louis DeJoy said the U.S. Postal Service is suspending operational changes, like removing mail processing equipment and collection boxes, until after the November election, as the agency tries to reassure Americans that it can handle the anticipated surge in mail-in voting.

Mr. DeJoy also said the agency won’t change retail hours at post offices across the country or close any mail-sorting facilities. He said overtime hours will continue to be approved as needed to process mail.
