Congressional Investigations

Congressional investigations can unfold quickly and carry significant legal, reputational, and operational consequences, demanding a coordinated and strategic response. DLA Piper supports organizations with the insight and experience needed to navigate these challenges efficiently and with confidence.

Our multidisciplinary team advises on a broad spectrum of congressional inquiries, ranging from the most complex, high-profile investigations to more targeted requests.

Whether conducting an internal investigation or risk assessment, responding to information requests and subpoenas, or preparing for testimony, we leverage our bipartisan, bicameral experience to help our clients achieve their business priorities.

Our team includes former members of Congress, investigators, senior staffers, and policy advisors who have led many high-profile government investigations. We understand how decisions are made and maintain active relationships with oversight counsels and committee staff across Capitol Hill – enabling us to actively track developments and shape effective response strategies.

DLA Piper has helped businesses navigate congressional investigations related to cybersecurity, higher education, geopolitical risk, supply chain integrity, antitrust, and data privacy, among other areas.

When congressional inquiries intersect with parallel investigations by the Department of Justice, the Securities and Exchange Commission, or state attorneys general, we collaborate with our litigation and regulatory teams to ensure a unified, risk-aware approach. The path we help your organization chart is focused on protecting your reputation and long-term goals.
