Peter J. Kadzik


Peter Kadzik is a partner in Venable's Government Division, focusing on the firm's Congressional Investigations Practice and working closely with the Investigations and White Collar Defense, Litigation, and Regulatory practices. He represents companies, institutions, executives, public officials, and other individuals in all aspects of congressional, federal, and state government investigations, as well as litigation. Peter uses his extensive experience in government and the private sector to advise clients on the interplay between government inquiries, private litigation, and communications challenges involving public policy, regulatory, and investigative matters that present his clients with substantial legal and business risks. He also provides strategic counsel to his clients to identify and minimize such risks.

Most recently, Peter was nominated by former President Barack Obama and confirmed by the U.S. Senate to serve as the Assistant Attorney General for the Office of Legislative Affairs (OLA) of the U.S. Department of Justice from 2014 to 2017, after joining the Department in 2013. In this capacity, he led OLA's efforts to manage the Department's relationships and advance the Department's interests on Capitol Hill, working closely with the Department's leadership offices, law enforcement components, U.S. Attorneys’ Offices, litigating divisions, and grant-making components on a variety of legislative and oversight matters. Peter also participated in Executive Branch-wide groups on issues of importance to the administration, and was the Department's liaison to the White House and Capitol Hill on legislative matters.

During Peter's tenure, OLA prepared Department witnesses for testimony in congressional hearings and nominees for confirmation hearings. He successfully led efforts to confirm Attorney General Loretta E. Lynch, Deputy Attorney General Sally Q. Yates, FBI Director James Comey, and Bureau of Alcohol, Tobacco, and Firearms Director B. Todd Jones, among others. He also prepared the Attorney General, Deputy Attorney General, and numerous high-ranking Department witnesses for congressional hearings on oversight matters and proposed legislation, and Peter testified on behalf of the Department on numerous occasions. He also managed the Department’s efforts on numerous pieces of legislation, including FISA reauthorization (USA Freedom Act), criminal justice reform, enhanced measures to prevent human trafficking, ECPA reform, the Judicial Redress Act, and reauthorization of the 9-11 Victims Compensation Fund.

Prior to serving in the Department of Justice, Peter spent more than 30 years in private practice focusing on antitrust and commercial litigation, congressional and internal investigations, corporate compliance, representation of clients on matters involving state attorneys general, and representation of various nonprofit organizations and trade associations on a variety of legal and policy matters. While in private practice, he was lead counsel in major antitrust and commercial cases, and served as liaison counsel for joint defense groups on behalf of numerous Fortune 100 companies. He also formed and advised several labor-management committees to advance the mutual interests of both in industries such as pharmaceuticals, oil and gas, steel, and timber.

While in private practice, Peter represented a diverse range of clients in antitrust and commercial litigation, as well as congressional, federal, and state government investigations.
