Sullivan & Cromwell represents companies and individuals in congressional investigations, including high-profile investigations of great importance.

The Congressional Investigations Group has a long history of guiding clients through their most critical investigations, bringing to bear insights from the Firm's pre-eminent transactional and litigation practices. This multidisciplinary approach provides clients invaluable insights on how best to navigate often-unpredictable investigations, providing the best results possible—on and off Capitol Hill.

S&C's advice is not limited to the four corners of the investigation: It extends to the broader effects that it may have on client operations, in litigation and other investigations, and in interactions with regulators.

Investigative Bodies
S&C has advised on investigations by many congressional committees and investigative commissions, including:

  • the Senate Permanent Subcommittee on Investigations;
  • the Senate Judiciary Committee;
  • the Senate Homeland Security and Governmental Affairs Committee;
  • the House Committee on Oversight and Government Reform; and
  • investigative bodies, such as the Financial Crisis Inquiry Commission.

Witness Preparation
The Firm has prepared many prominent witnesses for testimony, including:

  • chief executive officers and other executives from the world's foremost financial institutions and industrial companies;
  • witnesses central to national events, such as the 2008 financial crisis; and
  • Supreme Court justices, other judges and cabinet members in confirmation, oversight and investigative hearings.

S&C lawyers have handled congressional investigations from both sides of the dais:

  • as congressional staffers, including as chief counsel for the Senate Banking Committee; and
  • as officials in the executive branch, including in the White House and in the leadership of the Justice Department.
