The American Civil Liberties Union of Iowa has filed new court documents seeking a judge's order to keep Iowa Secretary of State Matt Schultz from using a federal immigration database to try to find voters registered in Iowa who may not be citizens.
Schultz received permission Aug. 14 from the government to access federal immigration records.
The ACLU is asking a judge to rule on its lawsuit filed last year or at least issue a temporary order to keep Schultz from using the data until the lawsuit can be decided.
The ACLU says Schultz doesn't have the authority under Iowa law to remove voters by comparing state records with federal immigration data.
Schultz believes Iowa could have people registered to vote who are not citizens.
