Federal Judge Refers Philadelphia DA Krasner to DOJ for Possible Criminal Investigation

U.S. District Judge Paul S. Diamond Jr. has referred Philadelphia District Attorney Larry Krasner and Deputy DA Matthew Stiegler to the U.S. Attorney’s Office for a potential criminal investigation. The referral stems from a 40-page memorandum issued on September 15, 2026, regarding the handling of a post-conviction case for Dennis Johnson. Diamond alleged that Krasner and Stiegler may have obstructed justice and conspired to present a false narrative to the court. Krasner has disputed the findings and intends to appeal, while the DOJ has not yet commented on the referral.
Key points
- Judge Paul Diamond disqualified Krasner and Stiegler from the Dennis Johnson case but allowed the DA's office to continue handling it.
- The judge alleged that Krasner pressured prosecutors to lie and threatened consequences for staff who reported internal conflicts.
- Krasner stated he 'respectfully and vigorously disagrees' with the court's findings and plans to appeal the decision.
- The referral was based on a 2009 murder conviction case where the DA's office previously sought habeas relief for the defendant.
- The U.S. Attorney’s Office for the Eastern District of Pennsylvania declined to comment on the potential investigation.
Background
This development follows months of scrutiny regarding Krasner’s Conviction Integrity Unit. In the summer of 2026, the Pennsylvania Supreme Court ordered the state attorney general to review cases where Krasner’s office sought to overturn convictions without proper reviews. Krasner, a former civil rights attorney who took office in 2018, has faced criticism from state and federal judges for pushing to overturn murder convictions. The current referral is part of a broader controversy involving his office's handling of post-conviction cases, including the Dennis Johnson case, which was initially filed for habeas relief in 2022.
How outlets are covering it
NBC News and The Morning Call (via AP) emphasize the judge's conclusion that Krasner and Stiegler may have violated the law, citing potential obstruction of justice and criminal conspiracy. 6abc Philadelphia highlights the 40-page memo and the judge's description of the actions as 'troubling,' noting that Krasner refused to refer the case to the Pennsylvania Attorney General despite potential conflicts of interest. Fox News focuses on the specific allegations of perjury and false statements, noting that neither man has been charged yet. All outlets report Krasner's statement disputing the findings and his intention to appeal, while noting the DOJ's lack of immediate response.
Why it matters
This referral represents a significant escalation in the ongoing controversy surrounding Philadelphia DA Larry Krasner's office. It marks the first time a federal judge has recommended a criminal investigation into a sitting district attorney for actions taken in a post-conviction case. The outcome could have broader implications for the handling of post-conviction cases across the country and may influence how other DA offices manage similar situations. It also raises questions about the independence of DA offices and the role of federal oversight in state-level criminal justice matters.
What to watch
The U.S. Attorney’s Office for the Eastern District of Pennsylvania will decide whether to open a formal investigation based on the judge's referral. Krasner has indicated he will appeal the judge's decision, which could delay or alter the course of the proceedings. The Dennis Johnson case remains on hold, and it is unclear which prosecutor from the DA's office will take over the case moving forward. The Pennsylvania Attorney General's office may also review the case, as ordered by the state Supreme Court earlier in 2026.
