Attorney General Eric Holder and the Justice Department filed a lawsuit on Tuesday challenging Arizona’s controversial new immigration law, arguing that it attempts to unconstitutionally supersede the authority of the Federal government.
The lawsuit claims that the "Federal government has preeminent authority to regulate immigration matters," and asks the court to issue an injunction to prevent the law from going into effect on July 29.
GOP leaders were quick to condemn the suit, which names both the state of Arizona and Governor Jan Brewer as defendants, according to Fox News.
Representative Darrell Issa (R-Calif.), the top ranking Republican on the Oversight and Government Reform Committee, called the decision to file the lawsuit "disgraceful," adding the Obama administration has ignored the plight of legal Arizona citizens who "now find themselves overrun by drug cartels, gangs and human trafficking."
The Grand Canyon state’s two Senators—John Kyl (R-Ariz.) and John McCain (R-Ariz.)—suggested that the lawsuit will force people to question whether the administration is fully committed to securing the United States-Mexico border, USA Today reports.
Meanwhile, the White House said later on Tuesday that President Obama and his staff were not involved in the lawsuit, implying the decision was made solely by Holder and other officials with the Justice Department, according to The Washington Post.
