OBrien Alicia

Alicia O'Brien provides strategic counsel in all aspects of congressional, federal, and state government investigations. A former senior advisor at the U.S. Department of Justice (DOJ), Alicia uses her extensive public and private sector experience to help clients navigate these high-stakes matters, which routinely involve complex legal issues, as well as public policy and media challenges. She also leads internal investigations and provides guidance on crisis management, proactive and remedial compliance measures, and mitigation of reputational damage and business disruption.

Alicia represents companies, institutions, executives, public officials, and other individuals facing investigations and enforcement actions by Congress, the DOJ and other executive branch agencies, state attorneys general, and federal inspectors general. She also engages regularly with federal and state public officials on policy and regulatory issues.

An astute strategist, Alicia manages all stages of these investigations, including wide-scale subpoena responses, witness preparation and testimony, and public messaging. She has developed relationships with public officials on both sides of the aisle throughout the course of her government positions and extensive advocacy for her clients.

Most recently, Alicia served as a key senior advisor at DOJ through her roles as an associate deputy attorney general in the Office of the Deputy Attorney General (ODAG) under Deputy Attorney General Sally Q. Yates, and as a deputy assistant attorney general in the Office of Legislative Affairs (OLA). In these capacities, she routinely advised the Department's leadership on high-profile, sensitive matters, and managed all aspects of the Department's responses to an exceptional volume of congressional oversight inquiries and investigations, and parallel inquiries by inspectors general, the Government Accountability Office (GAO), and other federal agencies.

In addition, Alicia regularly prepared DOJ's most senior officials, including the attorney general, deputy attorney general, associate attorney general, and U.S. attorneys, for numerous congressional hearings, member briefings, and other congressional engagement on a wide range of oversight and policy issues. In the 114th Congress, Department witnesses testified in more than 110 hearings, and one committee alone sent more than 200 oversight letters to the Department, containing nearly 2,000 separate requests for documents, briefings, and information. Alicia also played a key role in managing the Senate confirmation process for presidentially appointed Department nominees, including serving as a leading adviser to Attorney General Lynch and Deputy Attorney General Yates, among others.
