Before joining the Criminal Division, Jason served for nearly 10 years as an assistant US attorney in the US Attorney's Offices for the Southern District of New York and the District of Maryland, where he investigated and prosecuted cases involving financial crimes, public corruption, racketeering, cybercrime, national security, narcotics, money laundering, immigration offenses, and violent crime. In the District of Maryland, where he served as Assistant Chief of the Criminal Division and as Chief of the Violent Crime Section, Jason prosecuted many of the highest-profile cases of the past decade in Baltimore. He brings this experience to bear in each client matter, many of which are extremely prominent. Among other recent matters, he represents Volkswagen in the criminal case arising from the diesel emissions controversy and led the independent investigation by the board of Pilot Flying J in response to allegations of fraudulent sales practices.
