In June 2004, the Senate Finance Committee Staff circulated draft proposals to improve regulation of charities and requested comments from a number of experts in nonprofit law. In her response, Marion R. Fremont-Smith, Hauser Center for Nonprofit Organizations at Harvard, supported proposals to extend existing limitations and increase disclosure requirement. She urged caution before adopting proposals to expand the role of the IRS from its traditional one of protecting the integrity of the tax system to that of policing the internal practices of exempt organizations, and she strongly favored increasing information sharing between federal and state regulators, while opposing a suggestion to give enforcement powers to private individuals.
