Congressional Investigations

When Congress investigates, even the most sophisticated businesses feel as though they have fallen through the looking glass. Such investigations can have devastating implications for the course of law enforcement and other executive branch investigations, a company’s public image, filed or contemplated civil lawsuits, and a company’s business and regulatory interests involving the government.

Whether advising companies on how to appropriately respond to a congressional inquiry or subpoena, preparing and representing witnesses in connection with congressional testimony, interacting with an investigating committee, or managing the legal, policy, political, or public relations considerations outside of the investigating committee, Sidley Austin’s Congressional Investigations team has the necessary resources to help a client navigate this complex terrain.

Sidley was one of the first national firms to establish a significant presence in Washington, D.C. and has practiced law in the nation’s capital since the late 1960s. Since then, the firm’s lawyers have handled an array of congressional probes, including for clients caught up in many of the major political scandals of the past four decades. We possess the necessary combination of legal skill, political judgment, and applicable experience to handle the most difficult such matters ably.
