Governor Pat Quinn says he will sign a newly-approved pension overhaul into law "promptly."

The Chicago Democrat told reporters Tuesday that the bill estimated to save $160 billion over thirty years will help the state and its people. He calls it "landmark legislation."

Quinn has made pension reform a top priority for two years, but efforts had been unsuccessful including previous special sessions and a social media campaign. More recently, Quinn had refused to take a paycheck until lawmakers came up with a comprehensive solution.

When asked if he'll now collect his paychecks, he told reporters Tuesday that he hadn't thought about it yet.

Unions were opposed to the measure saying it's not constitutional.

Quinn says he thinks the bill will survive a court challenge.
