The U.S. Department of Justice has sued two more states this month to prevent them from implementing new state laws targeting immigrants. The lawsuits against Iowa and Oklahoma — in addition to one against Texas — signal that the Biden administration is taking an aggressive stance against states taking immigration matters into their own hands. Iowa and Oklahoma joined Texas in passing new state laws that charge undocumented immigrants with either a criminal misdemeanor or a felony for entering the country without authorization. The Texas case is likely to make it to the Supreme Court.
