From the Document: "International trophy hunting is a multinational, multimillion-dollar industry practiced throughout the world. 'Trophy hunting' is broadly defined as the killing of animals for recreation with the purpose of collecting trophies such as horns, antlers, skulls, skins, tusks, or teeth for display. The United States imports the most trophies of any country in the world. Congressional interest in trophy hunting is related to the recreational and ethical considerations of hunting and the potential consequences of hunting for conservation. For some, interest in trophy hunting centers on particular charismatic species, such as African lions, elephants, and rhinoceroses. Congress's role in addressing international trophy hunting is limited, because hunting is regulated by laws of the range country (i.e., the country where the hunted species resides). However, Congress could address trophy hunting through actions such as regulating trophy imports into the United States or providing funding and technical expertise to conserve hunted species in range countries."
