12 January 2015

Debevoise & Plimpton LLP today announced that David A. O’Neil, former Acting Assistant Attorney General for the Criminal Division and former Deputy Assistant Attorney General for the Fraud Section at the Department of Justice, has joined the firm as a partner in Washington, D.C. as a member of the firm’s White Collar & Regulatory Defense Group and Cybersecurity & Data Privacy practice.

Mr. O’Neil’s eight-year government career included increasingly high-profile positions within the DOJ. In 2014, he was designated by the President and Attorney General to lead the Criminal Division, where he was responsible for supervising more than 600 attorneys investigating and prosecuting the full range of federal crimes, including corporate malfeasance, cybercrime, fraud offenses and money laundering.

“David’s long and increasingly visible tenure in government service has given him broad experience and a sterling reputation in the kinds of cases that are at the heart of our White Collar & Regulatory Defense Group,” said Bruce E. Yannett, Deputy Presiding Partner of the firm and Chair of the White Collar & Regulatory Defense Group. “David’s front-line experience at the DOJ, including in the fields of cybersecurity and data privacy, will provide another tremendous asset to our clients and further expand our team of exceptional partners known for their expertise.”

Debevoise’s White Collar & Regulatory Defense Group excels in high-profile, complex representations for clients facing corporate crises. The Group’s depth of experience and global reach allows for effective and strategic counsel with international and domestic clients, from defending against criminal prosecutions and civil enforcement actions, to conducting internal investigations, negotiating complex global settlements and facilitating cooperation with government regulators. Ranked as a leading firm for Technology: Data Protection and Privacy by Legal 500 US, Debevoise assists clients with a broad range of privacy, data protection and data security matters. The cross-border, interdisciplinary team has special expertise in helping clients navigate the forensic and legal aftermath of data breaches.

“We are delighted to welcome David to Debevoise,” said Mary Beth Hogan, Co-Chair of the firm’s Litigation Department. “His impressive rise within the ranks of the Department of Justice is a testament to his superior legal judgment, work ethic and supervisory skills. David’s unique background in government enforcement will be invaluable to clients facing these critical issues.”

Mr. O’Neil has experience across a broad range of high-profile matters, including the most significant FCPA prosecutions, the LIBOR investigations and high-profile investigations of financial institutions for money laundering and Bank Secrecy Act violations. He is a Harvard law graduate who earned his bachelor’s degree at Princeton University and clerked for U.S. Supreme Court Justice Ruth Bader Ginsburg.
