ProPublica announced on Tuesday that Geraldine Sealey has been hired as a senior editor working with the Local Reporting Network. She starts on March 9.

“It is a joy to welcome Geraldine to ProPublica and to the Local Reporting Network team,” said Sarah Blustain, an assistant managing editor at ProPublica. “Her deep experience editing accountability projects will be a boon for us and for the local newsrooms with which she will be working.”

Sealey was most recently the longtime managing editor of The Marshall Project, where her editorial leadership produced journalism that won the Pulitzer Prize, a Pulitzer finalist citation, multiple National Magazine Awards, Online Journalism Awards, an Emmy nomination, Edward R. Murrow Awards and other major recognitions.

Sealey edited “Foster Care Agencies Take Millions of Dollars Owed to Kids. Most Children Have No Idea,” a 2022 Pulitzer finalist in national reporting that exposed how nearly every state was quietly seizing Social Security benefits owed to foster children. The impact was sweeping: More than a dozen states and municipalities established new rules or legislation to protect those benefits, and more than a dozen others introduced bills to conserve the money or require that children be notified before it was taken.

“How the Newest Federal Prison Became One of the Deadliest,” a collaboration between The Marshall Project and NPR that she edited, exposed violence and abuse in the Special Management Unit at a federal prison in Thomson, Illinois. Within two weeks of publication, Illinois members of Congress called for a Justice Department inspector general investigation. Months later, the Bureau of Prisons announced it would close the unit; ultimately, the entire prison was converted to minimum security. This year, the DOJ’s inspector general concluded that the Bureau of Prisons had violated its own rules through widespread misuse of restraints, and the agency agreed to revise its policies and practices.

Sealey also edited the narrative podcast “Violation,” a collaboration between The Marshall Project and WBUR in Boston that examined the parole system in the United States through a decades-old murder case. The series was nominated for a 2024 National Magazine Award.

Earlier in her career, Sealey served as enterprise editor for NBC News Digital, where she collaborated on a yearlong reporting project on poverty in America that won a Peabody Award. She began her career as an intern for a local television news station in her hometown of Scranton, Pennsylvania.

“I am ecstatic to join ProPublica, an organization I’ve long admired, and to partner with journalists across the country holding the powerful to account in their communities,” Sealey said.
