To extend the authority of the Secretary of Veterans Affairs regarding presumptions of service connection for diseases associated with exposure to herbicide agents, and for other purposes.

Agent Orange Exposure Fairness Act This bill reinstates and extends the authority of the Department of Veterans Affairs to determine and regulate diseases that warrant a presumption of service connection after exposure to a herbicide agent. Under a presumption of service connection, specific diseases diagnosed in certain veterans are presumed to have been caused by the circumstances of their military service. Health care benefits may then be awarded.
