U.S. District Judge Colleen Kollar-Kotelly blocked President Trump's executive order requiring proof of citizenship for voter registration, emphasizing that election authority lies with Congress and states, not the President. This decision came in response to lawsuits from various voting rights groups, who argued the order threatened to disenfranchise eligible voters. While the judge allowed some parts of the order to proceed, including tighter mail ballot deadlines, the ruling represents a significant win for electoral rights advocates amid ongoing controversies surrounding voter registration processes.
