Oral history on Illinois' most powerful politician launches

Why it matters: Madigan stepped down as representative earlier this year and is currently the focus of a federal investigation stemming from the bribery scandal at ComEd, though he has not been charged with any wrongdoing.

Flashback(s): He was notorious for understanding the rules of the Illinois government better than anybody. This might be because Madigan wrote many of the rules and was a delegate at the Illinois Constitutional Convention in 1970.

• Former Governor Jim Edgar named his heart attack after Speaker Madigan. He also recounts stories of lunches at the governor's mansion where all Madigan ate was an apple, cut up on a plate.
• Former Governor Bruce Rauner goes into detail about their monumental political fights, including a breakfast where Madigan said, "Bruce, I do two things. I manage power and make money from managing power."
