In United States politics, the Dickey Amendment is a provision first inserted as a rider into the 1996 federal government omnibus spending bill which mandated that "none of the funds made available for injury prevention and control at the Centers for Disease Control and Prevention (CDC) may be used to advocate or promote gun control." The amendment was lobbied for by the NRA. The amendment is named after its author Jay Dickey, a Republican member of the United States House of Representatives from Arkansas. Many commentators have described this amendment as a "ban" on gun violence research by the CDC. The amendment was introduced after lobbying by the National Rifle Association in response to the perceived bias in a 1993 study by Arthur Kellermann that found that guns in the home were associated with an increased risk of homicide in the home, as well as other CDC funded studies and efforts. In response to this amendment being adopted, the American Psychological Association adopted a resolution condemning it. In December 2015, multiple medical organizations, including Doctors for America, the American College of Preventive Medicine, and the American Academy of Pediatrics, called on Congress to repeal the amendment. That same month, the American Association for the Advancement of Science also called for an end to this amendment. Following the Sandy Hook Elementary School shooting in 2012, President Barack Obama directed the CDC and other federal agencies to "conduct or sponsor research into the causes of gun violence and the ways to prevent it." The CDC responded by funding a research project and conducting their own study in 2015. That month, a spokeswoman for the agency, Courtney Lenard, told the Washington Post that "it is possible for us to conduct firearm-related research within the context of our efforts to address youth violence, domestic violence, sexual violence, and suicide. But our resources are very limited."
