Jenner & Block

Andrew Weissmann is co-chair of the firm’s Investigations, Compliance and Defense Practice, with a focus on counseling companies at the highest levels in both domestic and global investigations and litigation.  He is a leading trial lawyer and investigator with deep experience in Foreign Corrupt Practices Act (FCPA) issues and compliance matters.  In an illustrious career that has included tenures as a federal prosecutor, Department of Justice Fraud Section chief and FBI general counsel, he has done ground-breaking work.

Before rejoining the firm in 2020, Mr. Weissmann served as a lead prosecutor in Robert S. Mueller’s Special Counsel’s Office.  

In addition to practicing law, he teaches criminal procedure and national security law at New York University School of Law, where he is a distinguished senior fellow.  He is also a legal analyst for NBC/MSNBC.

From 2013 to 2017, Mr. Weissmann served as the chief of the Fraud Section in the US Department of Justice Criminal Division.  In that role, he oversaw more than 125 white-collar prosecutors in three units: FCPA, Securities and Financial Fraud, and Health Care Fraud.

In 2011, Mr. Weissmann left Jenner & Block to serve as general counsel under then-FBI Director Robert S. Mueller.

During his tenure at Jenner & Block from 2006 to 2011, Mr. Weissmann represented domestic and international corporations and executives with criminal and civil investigations and compliance matters, including representations before the DOJ, the Securities and Exchange Commission, and state authorities.  He won several civil fraud arbitrations, one of which was at the time the largest Financial Industry Regulatory Authority (FINRA) arbitration award in history—approximately $430 million.

From 2002 to 2005, he was deputy and then director of the Enron Task Force in Washington, DC, where he supervised the prosecution of more than 30 individuals in connection with the company’s collapse.

Mr. Weissmann began his career as a prosecutor in the US Attorney’s Office for the Eastern District of New York.  In that role, he tried more than 25 cases, including members and leaders of the Colombo, Gambino and Genovese families.

Mr. Weissmann has made an impact in all his roles, devising and implementing significant corporate policies that remain in place today.  He crafted and launched the FCPA Pilot Program, now known as the FCPA Corporate Enforcement Policy, which defines and gives credit for corporate cooperation, voluntary disclosure of wrongdoing and effective corporate compliance programs.  The policy is also the basis for the National Security Division’s policy for corporate sanctions cases and for how the Antitrust Division evaluates compliance programs.  He also devised other measures that the DOJ’s Fraud Section applies to companies.
