SPRINGFIELD, Ill. (WBBM) — New proposed legislation aims to close the loopholes that have allowed some Chicago labor union leaders to collect massive public pensions.

Illinois House Republican Leader Tom Cross says pension double-dipping is illegal, but some union leaders may have falsified documents to say they were not receiving union retirement benefits.

The Oswego Republican has introduced bills to change a 1991 law that allowed union leaders to collect regional or international labor pensions while getting city benefits too.

He’s also proposed a bill outlawing the practice of collecting a city pension based on a high union salary.

Cross says he’ll be very aggressive in going after other pension abuses during the veto session later this month.
