“No one is entitled to another four-year term, you have to earn it,” Quinn said. “I think looking at the record, I decided, and I thought a lot about this, that the best person for the next four years to restore trust in the justice system is Kim Foxx.”

Quinn did endorse Anita Alvarez when she first ran in 2008. He says her handling of the Laquan McDonald case was a factor in his decision this time around.

Alvarez’s campaign manager said, “To the surprise of no one, career politician Pat Quinn, who has been the beneficiary of hundreds of thousands in campaign spending by Toni Preckwinkle, is now backing her political puppet Kim Foxx.”

Alvarez says she’s not seeking endorsements of politicians because she has kept politics out of her decisions while in office.

Donna More, a former local and federal prosecutor who is also running for state’s attorney, says she’s the only true independent.
