A just-released report looks at misconduct in the school system over the last year.
It found one high-ranking education official accepted $16,900 in cash, meals, even a scholarship to push the district to do business with certain vendors.
But CPS may not be able to sever ties with all of those vendors because some are so big no other firms can handle the work.
The Inspector General also found widespread fraud with the lunch program.
Twenty-one principals and assistant principals helped falsify applications so their students could receive free or reduced cost meals.
