Congressional Investigations


When you or your company are targeted for a congressional investigation, you confront a unique challenge. An investigation can present legal, reputational and business risks—both in the immediate congressional arena and in collateral venues, including private civil actions and criminal or civil investigations on the federal or state level.

Navigating the obscure rules and legislative precedents of congressional investigations, along with the individual personalities and interests of members of Congress, requires a blend of legal and political skill steeped in decades of practical experience. Drawing on that skill and experience, we tailor our approach to fit your circumstances, going beyond the strategies and tactics typically deployed in a courtroom or before a regulatory agency.
