Peter G. Wilson

Chicago Office

Peter G. Wilson has a broad litigation practice with a focus on government investigations and enforcement matters. He represents companies and individuals in regulatory investigations and enforcement actions, federal and state court litigation, and related internal inquiries.

Much of Peter's practice involves the financial services industry. He has represented investment banks, investment advisers, broker-dealers, proprietary trading firms, clearing firms, and their individual officers and employees in inquiries by the Securities and Exchange Commission, the Commodity Futures Trading Commission, the Financial Industry Regulatory Authority, the National Futures Association, and options and futures exchanges. Before joining Katten, Peter served in the Legal Division of the Consumer Financial Protection Bureau, and he draws on that experience to counsel banks and other lenders in regulatory inquiries and enforcement actions regarding consumer lending, including fair housing and truth-in-lending litigation.

Peter has particular experience representing public companies in governmental inquiries and related private litigation. He has conducted internal investigations on behalf of special litigation committees in response to shareholders' allegations of fraudulent accounting and financial reporting. He has also represented the independent compliance monitor appointed in connection with a significant Foreign Corrupt Practices Act settlement by a pharmaceutical company, and has overseen related inquiries in Latin America, Eastern Europe and Asia.

Peter also represents clients in criminal and civil inquiries by the Department of Justice and state attorneys general. He has represented companies and individuals in criminal inquiries into potential health care, securities, bank and wire fraud, and in investigations under the False Claims Act.

Peter began his career with the Legal Aid Society of the District of Columbia and maintains a strong commitment to pro bono work. He regularly represents asylum seekers in collaboration with the National Immigrant Justice Center (NIJC) and serves on NIJC's Junior Leadership Board.
