Judge Colleen Kollar-Kotelly blocked parts of the executive order adding a proof-of-citizenship requirement to the national voter registration form.

The blocked portion of the order would have changed the federal voter registration form to indicate proof of citizenship is required.

U.S. District Judge Colleen Kollar-Kotelly ruled that the Trump administration cannot enforce parts of the order requiring federal election officials to assess whether people who are registering to vote are citizens.
