NEW YORK (AP) — A 3,000-circulation newspaper that publishes twice a week has won the Pulitzer Prize for editorial writing.

The Storm Lake Times of Iowa and writer Art Cullen won for a series of editorials that challenged powerful agricultural interests in the state. Judges said Cullen’s editorials were fueled by “tenacious reporting, impressive expertise and engaging writing.”

The Pulitzers, in their 101st year, were announced Monday afternoon at Columbia University in New York City.
