A law in Arizona requiring proof of citizenship to vote is supported by 24 state attorneys general in an emergency stay with the Supreme Court.

Over 20 state attorneys general in the U.S. have filed amicus briefs with the Supreme Court in support of an emergency stay that would enable Arizona to mandate U.S. citizenship as a requirement for voting in federal elections.

The Arizona Republican Party filed an emergency application with the U.S. Court of Appeals Ninth Circuit on Thursday in support of HB 2492, which mandates proof of citizenship to vote in presidential elections.

Even if ballots are submitted via mail, Arizona law mandates the presentation of citizenship evidence.

"The Constitution grants states the authority to establish voter qualifications, and Arizona is taking the lead in ensuring that only citizens participate in elections," the Arizona GOP tweeted. "This decision has the potential to permanently prevent non-citizen voting, which should have been the standard from the beginning."

The brief was supported by 26 attorneys general, including those from Texas, Florida, and Virginia, among others.

The Dhillon Law Group submitted a brief arguing that the Constitution does not back the district court's decision and that it is lawful for a state to demand evidence of citizenship to participate in elections.

Harmeet Dhillon, the lead attorney for the law group, wrote that the Court should immediately halt the District Court's injunction that conflicts with Arizona's constitutional authority to appoint its presidential electors.

The Honest Elections Project believes that states have the right to require proof of citizenship for voting by mail and should be allowed to do so, according to their website.

The Republican National Committee has submitted an emergency application, stating that voter integrity is a pressing issue that has been overlooked, particularly due to the large number of "illegal immigrants" in the country.

"The number of non-citizen voters in the United States has likely increased due to the growth of the alien population. A study found that there were approximately 11 million illegal aliens in the country in 2019."

"The presence of aliens, whether they are here legally or illegally, represents a potential opportunity for voter fraud, as each one has a chance, however small, to vote illegally. Additionally, other sources of noncitizen voting, such as aliens who are legally present but cannot vote or those who have overstayed their visas, further exacerbate the issue."
