WICHITA — More than 116,000 people have signed an online petition urging the inspector general to investigate what it calls voter suppression at a federal government agency entrusted with making voting more accessible.

The progressive advocacy group CREDO Action said it planned to deliver petition signatures Wednesday to the U.S. Election Assistance Commission’s Inspector General Patricia Layfield.

The commission referred any comment to Layfield, who said in an email that she had not yet received the petition. She said she was not willing to comment on any of her office’s existing or planned projects.

At issue is the unilateral action by Executive Director Brian Newby that without public notice required residents of Kansas, Alabama and Georgia to provide documentary proof of citizenship to register to vote when using a federal form.
