Former Illinois House Speaker Michael Madigan (D) announced he will resign the seat he’s held for half a century at the end of the month, the Chicago Sun Times reports. “Madigan’s reign as the longest-serving leader in state or federal government ended last month after he was unable to secure enough votes to continue as House speaker.” “His fall from leadership came after federal prosecutors accused leaders at utility giant ComEd of bribing associates of Madigan in exchange for his organization’s help in passing favorable legislation.”
