SPRINGFIELD – An updated method of funding public schools in Illinois won wide Senate support Wednesday, but Gov. Bruce Rauner’s office came out in opposition to the plan, with the Republican’s education adviser maintaining that it would provide a “bailout” for Chicago schools to the detriment of other districts. The revamp of the 20-year-old school funding formula is part of what began in the Senate as a “grand bargain” compromise to break a budget deadlock.
