Anita Alvarez is expected to face three Democratic primary election challengers in her bid to remain Cook County's top prosecutor, but only she and Kim Foxx filed Monday.
Alvarez, a 7-year incumbent, filed papers Monday morning for re-election as state's attorney. At the same time, Foxx, a former assistant state's attorney, filed petitions to get on the ballot in an effort to unseat her former boss.
Foxx until recently was chief of staff to Cook County Board President Toni Preckwinkle, and worked in the state's attorney's office for 12 years.
Others expected to enter the race before the filing deadline next Monday are Donna More, a former state and federal prosecutor and attorney for the Illinois Gaming Board, and Cook County Commissioner John Fritchey, a former state assistant attorney general and state representative.
All four candidates appeared before Cook County Democratic Party leaders in August during the slatemaking process. Committeemen declined to make an endorsement, leaving it an open primary.
