Illinois congressional candidate Ann Callis' previous out-of-state residence has come under scrutiny, with a published report Sunday saying she signed mortgage documents while a judge in Illinois that listed her home as in Missouri.

Callis, a former Madison County judge, is trying to unseat Republican U.S. Rep. Rodney Davis in the district that stretches from Champaign to the St. Louis suburbs. The election is Nov. 4.

Reports indicate Callis signed multiple mortgage papers identifying her residence as a home in Kirkwood, Missouri, while a judge in Illinois. The newspaper cited copies of mortgage records it obtained.

Callis campaign spokesman David Miyashiro confirmed Callis signed the documents, but said they were limited in how much information they could show. The records show details of transactions by Callis and her husband, a St. Louis businessman.

Miyashiro said the Callis family listed the Missouri house because of limited space on documents.

He said Callis is a resident of Illinois and registered to vote in the state. She lived in a house she owns in Troy until moving to a rental house in Edwardsville for the campaign.

However Davis' campaign questioned the residency, alleging that Callis was being untruthful.
