The Trump administration has suffered its 21st consecutive court defeat in its effort to obtain voter rolls from US states, deepening a legal battle over who should control the nation’s elections. A federal judge in Washington, DC, ruled this week that states are not required to hand over unredacted voter records to the federal government. US District Judge Randolph Moss said the Constitution gives states the main responsibility for running federal elections. President Donald Trump has repeatedly claimed that widespread noncitizen voting benefits Democrats, although state audits and independent studies have found such voting to be rare. The Justice Department has sued more than two dozen states that refused to provide their voter rolls.
