SPRINGFIELD, Ill.  — A plan that was supposed to save millions in Illinois hasn’t.

An audit has found that the plan to save $500 million a year on state employee health insurance has actually cost an extra $10 million annually and isn’t even providing the service promised.

Auditor General Frank Mautino reported Wednesday that the idea by former Gov. Bruce Rauner’s administration was so ill-conceived and hastily orchestrated that its original intent changed, deadlines were missed, rules for minority participation were skipped and the online benefits portal created had glitches.
