SPRINGFIELD, Ill. - Illinois lawmakers tonight have begun patching together a budget for the fiscal year that started two weeks ago. The new spending plan doesn’t contain the tax increase that Gov. Pat Quinn has sought.

As a result, even supporters of the new budget generally admit it won’t get the state through the full fiscal year and will have to be revisited in the fall. It’s unclear how the plan will after thousands of potential state employee layoffs.

Among the provisions — which are being approved in House floor debate right now, with Senate approval likely later tonight — is a plan to borrow $3.5 billion to keep the state running.

It also includes a largely symbolic 12 unpaid furlough days for state lawmakers, after Quinn’s announcement last week that state workers will face 12 unpaid furlough days.

As has been the tradition in Springfield in recent years, legislative leaders withheld a floor vote on the budget for weeks, until the last possible moment –- Wednesday’s holdup of state employees’ pay –- then put the complex measure up for an evening floor vote with the intention of passing it within a few hours.

When House Speaker Michael Madigan, D-Chicago, asked state Rep. Bill Black, R-Danville, to be brief in his comments during floor debate, Black went on an angry tirade about the budget process under Democratic leaders this year.

“I want to know what the hell’s going to happen to people in my district . . . who can’t walk!’’ shouted Black, referring to threatened cuts of human services funding – and lingering questions about what the new budget does and doesn’t fund.

“You’ve had since March to do this!’’ Black screamed at his Democratic colleagues. “ . . . We should all be ashamed of what we’re doing here tonight at the last minute!’’
