A hearing is scheduled in a challenge of the home addresses listed by Congressional District 2 candidate Ann Kirkpatrick on her nominating petitions.
The hearing Monday stems from a lawsuit by three voters who allege that Kirkpatrick lives in downtown Phoenix, even though she listed two Tucson addresses on her nominating documents.
The lawsuit seeks to bar Kirkpatrick from appearing on the ballot for the Democratic primary in late August.
The Kirkpatrick campaign has called the lawsuit's claims baseless.
Kirkpatrick is a former member of Congress.
She gave up her seat representing northeastern Arizona in 2016 to make an unsuccessful challenge to Republican Sen. John McCain.
The 2nd District includes part of the Tucson area as well as Cochise County in the state's southeastern corner.
