A small-town Iowa newspaper with a staff of 10 people - most of whom are related to each other – has won a Pulitzer Prize for taking on powerful agricultural companies over farm pollution.... Cullen’s writing was lauded by the Pulitzer committee for “editorials fuelled by tenacious reporting, impressive expertise and engaging writing that successfully challenged powerful corporate agricultural interests in Iowa”. As well as hard-hitting news and editorials, the paper also includes local stories. On Monday, a front-page story told of how a second-grader found a four-leaf clover in the field behind her school. Cullen told the Washington Post that he knows what readers like. “We strive to have a baby, a dog, a fire and a crash on every front page, so, yes, we do pander,” he said.
