. For over a year, lawyer Bob Heist, then-chairman of the Milton Hershey School’s board, says he sought internal financial records detailing the spending history of the $17 billion charity, which has a mission to educate low-income students for free. He now says he is being denied records he needs as a board member charged with overseeing the Pennsylvania boarding school’s operations, and earlier this month he sued the school to obtain the documents. It’s an extremely unusual step for a sitting board member, taken against an extremely unusual institution: The Milton Hershey School is the wealthiest pre-college educational institution in the United States. It controls 80% of the Hershey Co. candy giant’s voting shares, and reaps profits from the sale of Hershey chocolate bars, Reese’s Peanut Butter Cups, and SkinnyPop-brand snacks sold in thousands of U.S. retail stores.
