Aisling O’Shea is a Special Counsel in the Firm’s Litigation Group. Ms. O’Shea’s practice
focuses on criminal defense, government investigations and the Foreign Corrupt Practices
Ms. O’Shea re-joined the Firm in 2017 after 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. Ms. O’Shea often handled active and covert investigations, pre-trial and grand jury proceedings, witness interviews and negotiated plea agreements. During her tenure at the Department of Justice, Ms. O’Shea led an investigation into corruption at Venezuela’s state-owned and controlled oil company and successfully prosecuted more than ten individuals, including several former Venezuelan officials, in connection with the investigation. The case, which won Homeland Security Investigation’s 2016 award for Outstanding Financial Investigation, resulted in the most individual convictions for a single
FCPA matter. Ms. O’Shea also successfully prosecuted two former financial executives, and reached a resolution with the financial institution, for conspiracy to commit securities and wire fraud.
Ms. O’Shea worked closely with every major U.S. Attorney’s Office and federal law enforcement agency, as well as 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 has also helped conduct trainings for U.S. and foreign law enforcement authorities related to the FCPA and money laundering.
