ProPublica announced on Thursday that veteran investigative journalist Ronnie Greene will serve as senior editor in Washington, D.C., and oversee a growing operation of journalists covering centers of power in the nation’s capital.

Greene joins ProPublica from Bloomberg Law, where he was a chief investigative correspondent and worked on a series of stories that revealed fraud in the $50 billion guardianship industry. Before that, Greene served as a Washington editor for Reuters and the Center for Public Integrity, where he oversaw a Pulitzer Prize-winning investigation that uncovered a system rigged by doctors and lawyers to deny benefits to coal miners stricken with black lung disease. At Reuters, he and his team compiled the most exhaustive database of jail deaths ever published, spotlighted squalid living conditions on U.S. military bases and revealed the staggering numbers of people killed in encounters with police who used Tasers.

Greene began his journalism career at The Miami Herald, where he played a reporting role in the paper’s Pulitzer Prize-winning coverage of Hurricane Andrew and Elián González’s return to Cuba. Nearly a decade later, he co-edited a series exposing deadly abuses and lax oversight in Florida’s assisted living facilities for the elderly and mentally ill, which was a finalist for the Pulitzer Prize for public service.

“Ronnie’s work has changed countless laws and lives and will be familiar to anyone who has followed accountability journalism over the last couple of decades,” Managing Editor Ginger Thompson said. “There’s never been a more important or competitive time for investigative reporting in Washington. We’re thrilled to have someone with Ronnie’s record for collegiality, excellence and impact to lead our work there.”
