WASHINGTON — Big-game hunters tapped by the Trump administration to help rewrite federal rules for importing the heads and hides of African elephants and lions as trophies defended the practice Friday, arguing that threatened and endangered species would go extinct without the anti-poaching programs funded in part by the fees wealthy Americans pay to shoot some of them. The International Wildlife Conservation Council had its first meeting. The Associated Press reported Thursday the advisory council appointed by Interior Secretary Ryan Zinke is stuffed with celebrity hunting guides, representatives from rifle and bow manufacturers, and wealthy sportspeople who boast of bagging the coveted “Big Five” — elephant, rhino, lion, leopard and Cape buffalo. One appointee also co-owns a private New York hunting preserve with President Donald Trump’s adult sons. Retired Oklahoma congressman Bill Brewster was unanimously selected as the board’s chairman.
