As I said, she released the documentation either late yesterday or today. But if you are looking for a coverup then check out this:

Former Weatherman and admitted terrorist William Ayers (whom Obama described in the Philadelphia debate as merely a "neighbor") was head of the operating arm of the CAC, working with Obama on distributing scores of millions of dollars to grantees in the wards of the city, and you have a topic that the Obama campaign wishes to avoid at all costs.
It took Stanly Kurtz, of National Review Online to ask permission to see the files held by the publicly-funded University of Illinois Chicago (UIC). After initially agreeing, The Richard J. Daley Library withdrew permission. Kurtz writes:
"The Special Collections section of the Richard J. Daley Library agreed to let me read them, but just before I boarded my flight to Chicago, the top library officials mysteriously intervened to bar access. Circumstances strongly suggest the likelihood that Bill Ayers himself may have played a pivotal role in this denial. Ayers has long taught at UIC, where the Chicago Annenberg Challenge offices were housed, rent-free. Ayers likely arranged for the files of the Chicago Annenberg Challenge to be housed in the UIC library, and may well have been consulted during my unsuccessful struggle to gain access to the documents."
