After three months, more than five dozen witnesses and an array of thorny legal scuffles, attorneys in the landmark corruption trial of ex-speaker Michael Madigan are slated to begin presenting closing arguments Wednesday.

In his testimony earlier this month, former House Speaker Michael Madigan cast himself as a champion of the working class, a consensus-builder who used his power to bring people together on legislation and protect constituents from greedy utilities and corporations.

Madigan, 82, and his co-defendant, political ally and confidant Michael McClain, are accused of running a criminal enterprise designed to enrich the former speaker and his associates and increase his political power.
