ProPublica announced Tuesday that Kit Rachlis is joining its national team as a senior editor. He will oversee a team of reporters to guide and elevate revelatory, important stories and projects. Rachlis starts on Aug. 30.

Rachlis joins ProPublica from the Atlantic, where he was a senior editor on the political desk. Before that, he spent six years as a senior editor at California Sunday Magazine, where he oversaw an array of notable stories. Among them: Nadja Drost’s “When Can We Really Rest?” which was recently awarded a Pulitzer Prize for feature writing, and work by ProPublica’s Joaquin Sapien, Lizzie Presser and Liz Weil.

Previously, Rachlis served as editor in chief of LA Weekly, Los Angeles magazine and the American Prospect and as a senior projects editor at the Los Angeles Times. Stories he edited have won a Livingston Award, a George Polk Award, a John Bartlow Martin Award, a James Beard Award, a PEN USA Award and a Front Page Award.

He has also edited more than a dozen books, most recently the New York Times bestseller “The Color of Law” by Richard Rothstein.

“Kit is a master of long-form narrative journalism that has accountability at its heart,” ProPublica Managing Editor Robin Fields said. “We’re thrilled to add him to our staff.”

“I’m thrilled and honored to be joining ProPublica,” Rachlis said. “No journalistic organization has done more important and consequential work over the last decade. I can’t wait to start.”
