IOWA CITY, Iowa (AP) -- Civil rights activists are seeking to block Iowa's Republican secretary of state from enacting rules to purge ineligible voters from Iowa's voter registration list and make it easier to report fraud.

The American Civil Liberties Union and the League of United Latin American Citizens filed a petition for injunction Wednesday to block Iowa Secretary of State Matt Schultz from enacting the rules, quietly issued July 20.

The first would allow Schultz to remove voters from Iowa's registration database by comparing that list against government databases of foreign nationals. The second would allow persons to report allegations of voter fraud through e-mail. The ACLU says state law requires a sworn statement.

The groups say Schultz is overstepping his authority and the rules could unfairly suppress voters. Schultz's spokesman had no comment.
