A federal judge on Thursday temporarily halted President Donald Trump from enacting some changes to how federal elections are run, including potential voters having to provide proof of citizenship when filling out a voter-registration form.

Democrats and voting rights groups sued the administration in March over such changes, alleging they unconstitutional and could silence Americans.

U.S. District Judge Colleen Kollar-Kotelly granted the plaintiff's preliminary injunction halting the changes while the lawsuit on the matter continues, according to The Associated Press.

The judge also blocked part of Trump's executive order that mandates public-assistance enrollees have their citizenship analyzed before getting a federal voter-registration form.

However, Kollar-Kotelly did not block the Trump administration from tightening the deadline for mail-in ballots.
