The Trump administration has asked the US Supreme Court to revive Arizona voting rules that lower courts blocked during Joe Biden's presidency, setting up what could become one of the most significant election-law battles before the 2026 midterms.
At the centre of the dispute are Arizona's proof-of-citizenship requirements and its process for removing suspected non-citizens from voter rolls. The Justice Department, which challenged the measures under Biden, is now backing efforts by Arizona Republicans and the Republican National Committee to restore them, marking a sharp reversal in the federal government's position.
