The decade-long FBI investigation that led to Madigan’s trial roiled local politics and changed the course of Illinois history.

The jury in the Michael Madigan corruption trial has reached unanimous verdicts on 17 counts against the powerful former Illinois House Speaker and his longtime confidant Michael McClain, but say they’re deadlocked on the remaining charges after some 64 hours of deliberations.

Madigan, 82, and his co-defendant and longtime confidante, Michael McClain, face a 23-count indictment in federal court in Chicago on charges of racketeering conspiracy, bribery, wire fraud, and attempted extortion.
