Illinois is racking up more debt than even its comptroller knows about. Hundreds of millions of dollars’ worth of bills are awaiting payment. They're part of a little-known program that has lawmakers asking questions.
Documents obtained by Illinois Public Radio show that, since November, the state owes businesses in the Vendor Support Initiative program more than $600 million. That doesn't include the 1 percent interest fee applied per month to bills over 90 days old under the Prompt Payment Act.
