As part of his effort on behalf of the former Iowa Army Ammunition Plant workers and their families, Grassley earlier this year petitioned the U.S. Department of Health and Human Services to object to a regulation that would make it harder for former IAAP workers to receive compensation. Grassley also personally questioned the Secretary of Energy about the department's management of the Energy Employees Occupational Illness Compensation Program and requested a review of the department's performance by the independent General Accounting Office.
