Illinois' second-richest man is backing Gov. Bruce Rauner's agenda, according to a campaign contribution filed on Monday.
Rauner is amassing enough money to dwarf that of his political foes.
Sam Zell sat out of Rauner's race for governor. State records show no listing of Zell giving any money leading up to the election last November.
But now Zell, a Chicago real estate and investment mogul, has come through with a record-setting $4 million contribution. Not to the governor himself, but to his new "Turnaround Illinois" Political Action Committee.
