Cheronis, who's defended alleged racketeers and international spies to movie moguls accused of sexual assault and a witness in the Madigan trial, Lou Lang, said putting Madigan on the stand is a risk. "You didn't have an idea that your precinct captain wasn't doing a lick of work for ComEd? Is that your testimony?" prosecutor Amarjeet Bhachu said.

Former House Speaker Michael Madigan is expected to face a tough cross-examination by prosecutors in his federal corruption trial Monday, in what promises to be a defining moment in the landmark case.

CHICAGO — Former Speaker of the Illinois House Michael Madigan faced his toughest test since deciding to take the stand in his public corruption trial. On Monday, prosecutors finally got their chance to cross-examine the 82-year-old who is charged with bribery, racketeering, wire fraud, official misconduct and other crimes.

Assistant U.S. Attorney Amarjeet Bhachu is one member of a larger team of prosecutors who summoned 50 witnesses in a bid to prove Madigan guilty. Still, the one-on-one exchange between the two men could prove to be one of the most pivotal moments of the trial.
