Government Service

Ms. O’Shea rejoined the Firm in 2017 after more than five years of service as a trial attorney in the FCPA Unit of the Fraud Section of the U.S. Department of Justice’s Criminal Division, where she focused on the investigation and prosecution of corporations and individuals related to FCPA violations, money laundering, securities and healthcare fraud, tax evasion and other complex economic crimes.  Over the course of her tenure at the DOJ, Ms. O’Shea worked closely with every major U.S. Attorney’s Office and federal law enforcement agency, as well as in coordination with other government agencies, including the U.S. Securities and Exchange Commission, FinCEN and the Office of Foreign Assets Control, and numerous foreign law enforcement and regulatory authorities. She also conducted trainings for U.S. and foreign law enforcement authorities related to the FCPA and money laundering.
As a federal prosecutor, Ms. O’Shea led a complex FCPA and money-laundering investigation into corruption at Venezuela’s state-owned and controlled oil company and successfully prosecuted more than twenty individuals, including several former Venezuelan officials, in connection with the investigation. The case, which won Homeland Security Investigations’ 2016 award for Outstanding Financial Investigation, resulted in the most individual convictions for a single FCPA matter. She also successfully prosecuted two former financial institution executives, and reached a resolution with the financial institution, for conspiracy to commit securities and wire fraud.
Prior to her government service, Ms. O’Shea was an associate at Sullivan & Cromwell where she also focused on complex financial investigations.
