CHICAGO (AP) — The daughter of Illinois state Rep. Cynthia Soto and a man have been charged in an attack that left one of Soto’s political rivals with a broken nose and other injuries.

Jessica Soto and Bradley Fichter, both 26, were charged Friday with three counts of aggravated battery. Fichter also faces a charge of filing a false police report following the March 6 attack on 30-year-old Robert Zwolinski.

Frank Avila, Jessica Soto’s lawyer, disputed the charges against his client, adding she and Fichter acted in self-defense.

The attack left Zwolinski with a black eye, broken nose and six stitches to his forehead.

Zwolinski challenged Cynthia Soto in Tuesday’s Democratic primary, but was defeated.

Prosecutors say Zwolinski was attacked after he saw Soto and Fichter putting Soto’s mother’s campaign signs outside his Chicago campaign office.
