US District Judge Indira Talwani blocks major parts of President Donald Trump’s executive order, preventing a federal voter list and new limits on mail-ballot delivery from taking effect in 23 states and the District of Columbia.The order would have required the Department of Homeland Security to compile citizenship-based voter lists, forced states to submit mail-voter rolls early and attach tracking barcodes, and directed the US Postal Service to deliver ballots only to voters on approved lists while asking the Department of Justice to prioritize prosecutions.States and voting rights groups sued, arguing the order exceeds presidential authority, risks false positives that could remove eligible voters and imposes costly compliance burdens; Postmaster General David Steiner testified that the US Postal Service would follow court injunctions.The ruling follows a separate decision by a Trump-appointed judge in Washington that declined a preliminary block as premature, and it accelerates appeals that will shape how states administer federal elections ahead of November.
