Billionaire businessman Sam Zell has donated $4 million to Illinois Gov. Bruce Rauner's new political action committee.
Documents filed Monday with the Illinois State Board of Elections show Zell is the first donor to the Republican governor's fund, called Turnaround Illinois.
Rauner created the political action committee to help push his pro-business agenda in the Democratic-controlled Legislature. The money will be used to support lawmakers and candidates who back his agenda and to oppose those who do not.
Among Rauner's legislative priorities are curbing the power of labor unions, lowering the cost of workers' compensation insurance and freezing property taxes. He also wants to move public employees from pensions to a less-generous 401(k) style retirement fund.
The committee is separate from Rauner's own campaign fund, which has about $20 million.
