Facing a handful of discrimination lawsuits from former prosecutors, Philadelphia District Attorney Larry Krasner has turned to Schnader Harrison Segal & Lewis for backup.

Last week, several attorneys from the Philadelphia-based litigation firm entered appearances for the city’s top prosecutor in four lawsuits filed several months ago by ex-assistant district attorneys each claiming to have been fired because of their age. The four lawsuits, which are on behalf of six former prosecutors, are pending in the U.S. District Court for the Eastern District of Pennsylvania.
