Update: Illinois Public Radio's Amanda Vinicky reports via Twitter that the two lobbyists in question - David Piccioli and Steve Preckwinkle - believe the pension reform bill is unconstitutional and are reviewing legal options.
The Illinois General Assembly has sent legislation to Gov. Pat Quinn that would curb pension abuses.
The Illinois House has voted to crack down on public pension abuses.
Lawmakers voted 111-3 Thursday to prevent public employees who served in union positions from receiving pensions from both the government and the union.
The measure sponsored by House Minority Leader Tom Cross also limits the size of pensions. An employee who takes a leave of absence from his public job to serve in a union post must receive a pension based on his public salary before the leave -- not the higher union salary.
