Jon King's primary focus is on white collar crime, including the Foreign Corrupt Practices Act (FCPA) and related issues involving corporate compliance and internal investigations. Jon co-chairs DLA Piper's Global Investigations practice, ranked among the top global investigations practices by Global Investigations Review (GIR). He previously co-chaired DLA Piper’s White Collar, Corporate Crime and Investigations practice.

Over the course of the nearly two decades since he left service as a federal prosecutor, Jon has directed and conducted numerous cross-border investigations of FCPA and other anti-corruption and fraud issues in a wide variety of sectors, among them energy, industrials, and life sciences, in locations all across the globe. He is a well-known FCPA and white collar practitioner who is Chambers-ranked and has been recognized for his investigations work by GIR’s Who’s Who Legal, which describes Jon as "a go-to practitioner for sophisticated investigations work, with impressive knowledge in high-stakes regulatory enforcement actions and corporate compliance."

Jon has negotiated and obtained no-action decisions from US law enforcement authorities and has negotiated global resolutions of anti-corruption matters with law enforcement authorities outside the US. He also assists his clients with a wide variety of other FCPA and other anti-corruption related issues, including the development of effective compliance programs, due diligence issues and general FCPA advice.

In addition to his work on FCPA and global anti-corruption issues, Jon has conducted numerous corporate internal investigations on behalf of corporations and other entities, as well as corporate boards of directors and audit committees. Jon serves as counsel to individuals and businesses on numerous white collar matters involving domestic public corruption, corporate fraud and abuse, criminal antitrust, securities fraud, including insider trading and accounting irregularities, criminal tax and other regulatory and compliance matters, including trade controls, insurance and financial services-related issues. Jon regularly represents both individuals and businesses in connection with grand jury investigations conducted by the US Department of Justice, investigations and enforcement actions brought by the US Securities and Exchange Commission, and investigations and prosecutions brought by other state and federal agencies.

Prior Experience

Prior to joining DLA Piper in 2002, Jon served for more than eight years as an Assistant United States Attorney in Chicago and for nearly four years as an Assistant State's Attorney in the Cook County State's Attorney's Office. Before embarking on his career as a government lawyer, Jon was in private practice.

Before leaving the US Attorney's Office, Jon's most recent work on behalf of the government involved the investigation and prosecution of high-profile public corruption cases. At the time Jon left the Office, he was assigned to the Public Corruption Section, where he was fully devoted to the prosecution of such cases.

Before serving in the Public Corruption Section, Jon was assigned to the Special Prosecutions Section. There, in addition to handling corruption cases, he was also responsible for the investigation and prosecution of complex financial crimes involving fraud and other white-collar offenses. In this capacity, Jon conducted investigations involving frauds and thefts, including Ponzi schemes, commercial kickbacks and tax and bankruptcy frauds. For example, Jon directed an FBI investigation into the conduct of several employees of a major manufacturer of medical devices, who created and carried out a scheme to steal devices from their employer and local hospitals and then to sell these devices, for millions of dollars, in a diversionary market.
