DES MOINES (AP) — After a lawsuit and a barrage of criticism, Iowa’s top elections official on Wednesday dropped key parts of rules governing how his office will remove foreign nationals from the state’s voter registration database.

Three weeks after a presidential election that put Iowa in the national spotlight, Republican Secretary of State Matt Schultz announced changes to rules that spell out how his office will use a federal database to verify the citizenship of ineligible non-citizens and remove them from the rolls.

“The tremendous amount of public attention and input has been helpful in fine-tuning the original administrative rules filed this summer,” Schultz said in a statement.
