A federal judge on Friday extended an order blocking the U.S. Postal Service from implementing a new mail-in voting rule, allowing states already sending ballots to continue without federal approval. Judge Talwani’s order remains in place indefinitely while litigation continues and is expected to be appealed to the Supreme Court. The Trump administration has asked the high court to lift an earlier 14-day block, but Justice Ketanji Brown Jackson ordered opponents to respond by Tuesday morning, making an immediate ruling unlikely. The rule would require states to send USPS voter names, addresses and ballot barcodes before mailing ballots, with the federal government retaining the information and returning noncompliant ballots to election officials. It would not change state eligibility rules. A whistleblower’s attorneys warned that a rushed portal rollout and a zero-percent barcode failure policy could delay or invalidate entire batches of ballots, while USPS said it was reviewing the concerns and had developed the portal consistently with court orders. Voters would not need to change how they request ballots, but officials and voting-rights groups warned of delays, particularly for rural communities, older voters, disabled voters and some recently naturalized citizens. The requirements would exempt U.S. military and overseas voters and would apply only to general elections, not primaries.
