 The new president of Panama is making a big promise. Jose Raul Molino says he'll close the Darien Gap to migrants. The notorious jungle region which connects Panama to Colombia has long been a route for migration to the United States from South America, but it has become extremely crowded. More than half a million people made the trek last year, according to the government in Panama. President Molino also says he'll work with Washington to prevent migrants from heading to the southern U.S. border. Juan Papier with Human Rights Watch in New York
