O’Melveny’s Congressional Investigations team is a trusted ally to companies, organizations and individuals responding to Congressional investigative subpoenas, facing ethics inquiries and related criminal investigations, and preparing for testimony at Congressional oversight hearings.

Our clients benefit from a team of talented lawyers with decades of government experience and creative approaches to investigations—lawyers who are equally well equipped to help clients manage their public relations, political strategy, and collateral litigation. We routinely handle complex, high-profile investigations; for example, we recently handled an investigation that included a nationally televised hearing, witness interviews, and document productions to four different, simultaneous investigations by House and Senate committees. And with experience that extends well beyond Congress, we also routinely represent corporations, audit committees, individual officers and directors, and others in internal, SEC, DOJ, and state attorney-general investigations.

Our team is led by K. Lee Blalack, II, a former chief counsel and staff director of the US Senate’s Permanent Subcommittee on Investigations, and David Leviss, a former chief investigative counsel who held high-ranking investigative positions on two US House of Representatives committees.
