A federal judge barred the Trump administration from requiring proof of citizenship to register to vote on Wednesday, marking the latest loss for the president’s election policies in recent months.

U.S. District Judge Denise Casper, an appointee of former President Barack Obama, issued a permanent injunction blocking a March 2025 executive order from President Donald Trump, which required a person to present proof of citizenship to register to vote. She sided with the coalition of Democrat-led states that sued over the order, claiming the states, rather than the president, have the power to control election procedures.
