Congressional Investigations and Oversight


Congressional investigations present unique challenges and pitfalls. Wiley Rein has the experience, resources, and expertise to manage effectively this perilous and often unfamiliar process. Our Team regularly represents a range of corporate clients and their executives in all stages of congressional proceedings. Whether responding to a subpoena or request for information, preparing for interviews, or assisting with testimony before a U.S. Senate or House Committee, our Team knows how to navigate the process. Wiley Rein also proactively seeks to help position our clients to identify, respond to, and shape anticipated investigatory activities.  

Our Congressional Investigations attorneys include former federal and military prosecutors, congressional counsel, government contracts counsel, and former legislative counsel and congressional staff members, among others intimately familiar with the process. Our lawyers have worked for some of the principal investigatory committees of both the House and the Senate, including the U.S. Senate Committee on Commerce, Science, & Transportation and the U.S. House of Representatives Energy & Commerce Committee. We continue to interact regularly with Senate and House Committees. We enjoy strong relationships with policymakers in Congress, including members of the Senate Committee on Homeland Security & Governmental Affairs and the House Committee on Oversight & Government Reform. We intimately understand both the spoken and unspoken rules by which congressional investigations are conducted. Our many years of experience and extensive network within Washington, DC provide critical insight in negotiating with staff members on the Hill to ascertain and limit the scope of requests for documents or interviews. 

Congressional investigations and oversight activities can be critical to advancing our clients’ interests on a variety of topics. As regulatory and congressional agendas increasingly intersect, marrying congressional and legislative savvy with a deep bench of subject matter expertise can yield optimal outcomes for clients.  Litigation and agency activity, from regulation to enforcement, can result in oversight and investigations. Conversely, oversight can shine a light on otherwise unreviewable agency activity and shape regulators’ policy agendas. Wiley Rein has helped industries and companies pursue multi-pronged strategies on the Hill and in agencies to drive regulatory activities and litigation and manage their associated challenges. We also help our clients navigate investigations by the Government Accountability Office in order to prevent them from becoming full-fledged congressional investigations. We have relationships with and expertise before many of the federal agencies setting the agenda for industry, including the Federal Communications Commission, the General Services Administration, the Environmental Protection Agency, the Department of Justice, and the Department of Defense, among others. In addition, Wiley Rein maintains a staff of experienced and effective political consultants, including former members of Congress and staff, who are able to assist with managing the political and media-related aspects of a congressional investigation. Wiley Rein’s subsidiary – SIGNAL Group – also provides an expanded network and supplemental congressional investigation resources, particularly in crisis management. As a Washington, DC-centric firm, we are perfectly positioned to address the multi-faceted assaults our clients often face from the government.
