Foxx defeated former state and federal prosecutor Donna More and embattled incumbent Anita Alvarez in the hotly-contested March Democratic primary.
“This is an honor and a privilege to be a child of Cabrini standing before you,” Foxx said Tuesday night after declaring victory.
“You have to be relentless when you grow up in the projects of Cabrini Green,” she said.
Alvarez came under fire for her handling of the controversial Laquan McDonald case. McDonald, a Chicago teen, was shot and killed by Chicago police officer Jason Van Dyke in October 2014.
Prior to running for state’s attorney, Foxx served as an assistant Cook County state’s attorney for 12 years. More recently, she served as chief of staff for Cook County Board President Toni Preckwinkle.
During her time under Preckwinkle, Foxx was the lead architect of the criminal justice reform agenda that deals with racial disparities in the criminal justice system.
The Chicago native, who was raised in the Cabrini-Green housing projects, received high-profile endorsements from the Chicago Tribune, Chicago Sun-Times and a host of elected officials, including Sen. Dick Durbin.
