In the late 1970s Congress began to address the effects of exposure to Agent Orange, a chemical defoliant used by the United States military during the Vietnam War. Congressional committees interviewed Vietnam veterans and consulted medical experts to explore possible links between Agent Orange and certain forms of cancer and other health problems. After experts confirmed the product was harmful to humans, Congress mandated the Department of Veterans Affairs to conduct further research on consequences of Agent Orange exposure and passed laws providing benefits to injured veterans.
