Illinois Senate Democrats sent a bill that would overhaul the state's school funding formula to Gov. Bruce Rauner's desk Monday.
The Republican governor has said he'll use his amendatory powers to rewrite the bill and send it back to the Senate over objections to funding for Chicago Public Schools. But he's repeatedly declined to specify what exactly he'll do.
To overrule Rauner, a three-fifths majority is needed. If that attempted fails, the bill dies.
Lawmakers convened Monday for the fourth day of a special session on school funding.
A new formula is required as part of the budget that legislators approved earlier this month. Without a new calculation, schools won't get paid. The first payment to schools is due Aug. 10.
