Ex-House Speaker Michael Madigan is set to return to the stand Wednesday morning, continuing testimony that will surely be some of the most crucial and closely examined of the bombshell public corruption trial.

During his testimony, Mike Madigan denied any involvement in a quid pro quo arrangement with former Alderman Danny Solis, who is a key government witness in the case.

Mike Madigan and Mike McClain have known each other since they both were state representatives in the 1970s, but their decades of friendship is now strained in the face of multiple corruption charges.
