The general manager of one of the largest public radio stations in the United States resigned Friday amid allegations of mismanagement. Jane Christo had helped create such well-known shows as Car Talk and The Connection, but controversy began to grow when she announced plans to sell off a smaller public radio station in Rhode Island. According to audited financial statements that WBUR files with the Corporation for Public Broadcasting, WBUR has a deficit of $12.4 million. There are additional allegations that jobs and valuable contracts were given to family members. NPR's Chris Arnold reports.
