Mayer Brown regularly represents clients in high-profile congressional investigations. These investigations can present significant reputational risks to companies and individuals, produce documents and witness statements that can be used to further civil litigation and even criminal prosecutions, and lead to adverse legislative and regulatory outcomes. Recognizing the unique nature of congressional investigations, our practice is composed of experienced lawyers and other professionals who know how to manage the political, regulatory, and media aspects of a congressional investigation, which can differ substantially from other types of litigation and investigations.

We recognize that successful responses to congressional investigations require advisers who can handle both the “congressional” and the “investigations” aspects. The members of Mayer Brown’s cross-practice and bipartisan Congressional Investigations team are experienced former congressional and administration officials and former prosecutors who have been key players in dozens of investigations and hearings while in government as well as in private practice. We are strategic thinkers who can anticipate how congressional committees will conduct investigations and hearings and help clients manage, and possibly avoid, the risks presented by an investigation. We have deep experience in helping clients navigate the publicity generated by congressional investigations and hearings, recognizing that negative publicity can tarnish a company’s reputation as badly as – or even worse than – an  adverse judgment in court.

Our team includes:

  • A former chief counsel and deputy staff director for the US Senate Banking Committee who also served as a US National Economic Council (NEC) deputy director
  • A former deputy enforcement director at the Consumer Financial Protection Bureau (CFPB)
  • Several former senior counsels on key congressional committees, including the Senate Judiciary and Homeland Security Committees and the House Ways & Means and Energy & Commerce Committees
  • A former US Trade Representative and US Secretary of Commerce
  • A former chief of the Watergate Special Prosecutor’s Task Force and member of the 9/11 Commission
  • Former General Counsel of the US Department of Commerce
  • Former Chief Counsels for the National Highway Traffic Safety Administration
  • A former manager for the Office of Legislative Affairs at the US Department of the Treasury
  • Former federal prosecutors

We have significant experience preparing witnesses for congressional hearings, responding to congressional subpoenas and document requests, and navigating the political and legal complexities arising from any parallel litigation or criminal and regulatory investigations. Our deep experience is why, time and again, clients that are the subjects of these investigations have chosen Mayer Brown to guide them and protect their interests. Indeed, we have acted on some of the highest-profile congressional investigations of their day.

Simply put, Mayer Brown has the experience to help clients when congressional investigators start asking questions.
