Justice Department sues Arizona over voter citizenship law

The Department of Justice filed a lawsuit against Arizona in an attempt to block a law requiring voters to show proof of citizenship before casting their ballots in federal elections.

The DOJ argues the requirement is "a textbook violation of the National Voter Registration Act," according to The Hill.

Arizona Republican Attorney General Mark Brnovich responded to the lawsuit on Twitter: "It’s another round of Brnovich v. Biden as his DOJ continues its attempts to undermine our election integrity laws. I will see you in court. Again."

Brnovich, who is running in the state's GOP U.S. Senate primary, has promised before that his office will "do everything in our power to push back against the lawlessness of the Biden Administration."

The Biden administration claimed Arizona's voter integrity measure is regressive.

"For nearly three decades, the National Voter Registration Act has helped to move states in the right direction by eliminating unnecessary requirements that have historically made it harder for eligible voters to access the registration rolls," Assistant Attorney General Kristen Clarke said in a press release about the lawsuit. "Arizona has passed a law that turns the clock back on progress by imposing unlawful and unnecessary requirements that would block eligible voters from the registration rolls for certain federal elections."

Arizona Republican Rep. Andy Biggs expressed his shock over the lawsuit. 

"DOJ doesn't think you should prove that you're an American to vote in an American election. DOJ is suing Arizona over proof of citizenship requirements," he wrote. "Unbelievable."
