DES MOINES, Iowa (AP) — The U.S. Justice Department sued Iowa on Thursday over its new law that would give the state the authority to arrest and deport some migrants, making it the second lawsuit filed in a single day that seeks to block legislation passed earlier this year by state lawmakers.

Both the Justice Department’s lawsuit and another suit filed by civil rights and immigrant rights groups argued the state law was preempted by federal law and should be declared invalid.

“Iowa cannot disregard the U.S. Constitution and settled Supreme Court precedent,” Principal Deputy Assistant Attorney General Brian M. Boynton, head of the Justice Department’s Civil Division, said in a statement. “We have brought this action to ensure that Iowa adheres to the framework adopted by Congress and the Constitution for regulation of immigration.”

The federal action was expected, as the Department of Justice warned Iowa’s top officials last week that the agency would sue unless they agreed not to enforce the new law. The law is similar to a more expansive Texas statute that has been challenged by both the Justice Department and civil rights groups.

The Justice Department lawsuit was filed on the same day the ACLU of Iowa, national ACLU and the American Immigration Council filed suit to to block the law on behalf of the Iowa Migrant Movement for Justice and two individual Iowans.

“This ugly law is deeply harmful to Iowa families and communities,” said Rita Bettis Austen, legal director of The American Civil Liberties Union of Iowa. “Iowa lawmakers knowingly targeted people who are protected by federal immigration laws and who are legally allowed to be here.”

Iowa Attorney General Brenna Bird said Thursday that the state would not back down, and that the law existed because President Joe Biden hasn’t secured the southern border.

“Iowa’s law is not unique; it simply enforces immigration laws while Biden refuses to,” Bird said in a written statement. “Iowa stands ready to defend our immigration law that keeps Iowa communities safe.”

The Iowa law has increased fear among immigrant communities in the state that enforcement would lead to racial and ethnic profiling, complicate interactions with police or dissuade community members from reporting crime. Activist and advocacy groups, including one named in the suit, have hosted gatherings to try to answer people’s questions and organized protests in response.

Texas was allowed to enforce the law for only a few confusing hours in March before it was put on hold by a federal appeals court’s three-judge panel. The panel heard arguments by both supporters and opponents in April, and will next issue a decision on the law’s constitutionality.

Some law enforcement officials and legal experts have said unanswered questions remain about how the laws in Iowa and Texas would be implemented, since enforcement of immigration law has historically fallen to the federal government and is a binational process.

The Iowa law, which goes into effect on July 1, would allow criminal charges to be brought against people who have outstanding deportation orders or who previously have been removed from or denied admission to the U.S. Once in custody, migrants could either agree to a judge’s order to leave the U.S. or be prosecuted, potentially facing time in prison before deportation.

The federal lawsuit states that because the Constitution assigns the task of regulating immigration and managing international borders to federal government, the state law should not be enforced.

The Iowa lawsuit also contends that the law conflicts with federal law and could direct police to arrest people who are authorized to be in the U.S., such as people who have been granted asylum or have visas. The suit said the law could result in the prosecution of children brought to Iowa by their parents.

“It will create absolute chaos and human suffering in our legal system, and harm Iowa communities,” said Melloy Goettel, legal director at the American Immigration Council.

Gov. Kim Reynolds, a Republican who signed the new legislation into law, reiterated her support for the change.

“As Governor, I have a responsibility to protect the citizens of Iowa,” Reynolds said in a written statement that repeated the arguments of other Republican leaders. “Since President Biden refuses to enforce our nation’s immigration laws — threatening the safety of our citizens — Iowa will step in.”
