EXPLAINER: Postal Service, judge at odds over ballot search

The U.S. Postal Service says it can't meet a federal judge’s order to sweep processing centers for undelivered mail-in ballots. It is arguing that doing so would be disruptive to its Election Day operations and that it had “physical and operational limitations.” Disputes about mail ballots, particularly those received after Election Day, could be the fuel for court fights over election results in some states.
