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.

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 Speaker of the Illinois House Michael Madigan faced his toughest test since deciding to take the stand in his public corruption trial.
