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 U.S. Rep. Rodney Davis (R-Taylorville) in the district that stretches from Champaign to the St. Louis suburbs. The election is Nov. 4.

Callis, according to documents obtained by Lee Newspapers, signed multiple mortgage papers identifying her residence as a home in Kirkwood, Mo., while a judge in Illinois. The Callis campaign says 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.

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