ProPublica announced on Wednesday that Andy Mannix has been hired as a reporter based in Minnesota. He starts on Feb. 2.  

Mannix joins ProPublica after 10 years at The Minnesota Star Tribune. His series on abuses in Minnesota prisons led to the state’s first-ever set of laws governing solitary confinement. He wrote at length about emergency doctors who promoted the dubious science of “excited delirium,” some while on the payroll of a police weapons manufacturer, prompting a federal investigation and contributing to a new law prohibiting law enforcement training on the diagnosis across Minnesota. In 2020, he was part of the team that covered the murder of George Floyd and the unrest and trials that followed, for which the paper won the George Polk Award and the Pulitzer Prize for breaking news. 

In November 2025, Mannix partnered with ProPublica reporter Jessica Lussenhop and Star Tribune photographer Leila Navidi on an investigation of a Minnesota church whose leaders protected a member of the congregation who had sexually abused several children. The story has prompted a Minnesota lawmaker to call for stronger mandated reporting laws.

“We’re excited to welcome Andy to the Midwest team,” said Deputy Midwest Editor Steve Mills. “Minnesota is a hotbed of news now and Andy has a long record of doing important accountability journalism. Having Andy in the Twin Cities will allow us to continue our investigative work there.”

“Andy is a dogged investigator with a wide range of skills,” said Midwest Editor George Papajohn. “The common thread in his impressive body of work in Minnesota is a quest to expose injustice. He’s a great addition to our talented team.”

Mannix started his journalism career at the Minneapolis alternative weekly City Pages, where he wrote narrative investigative stories. He has also written for The Seattle Times, MinnPost, Time and The Minnesota Daily. He studied journalism at the University of Minnesota, and holds a master’s degree from the University of California, Berkeley, where he focused on investigative and data-driven journalism. He also teaches as an adjunct at the University of Minnesota’s Hubbard School of Journalism.

“The flurry of recent national news out of Minneapolis is just the latest indicator of how critical the Midwest is to understanding the changing story of America,” said Mannix. “I am elated to be joining such a talented group of people who share my passion for uncovering these stories.”
