Jenner & Block Named to GIR 100 2020

For the sixth consecutive year, Jenner & Block has been named to the GIR100, Global Investigation Review’s “annual guide to the world’s leading cross-border investigations practices.” The profile charts the firm’s continued strength in this area, building on decades of experience handling the most complex government-facing and internal investigations, including the Lehman Brothers Holdings bankruptcy proceedings, the investigation into General Motors' ignition-switch recall and United Airlines' public corruption probe.

In addition to emphasizing the team’s track record handling complex FCPA and UKBA-related investigations, GIR also notes the team’s representation of Huawei as well as “significant experience representing clients in public corruption, food and drug safety matters, and financial and health care fraud investigations.” The practice is also singled out for its deep experience in corporate monitorships, including Thomas J. Perrelli and Neil M. Barofsky’s roles as monitors of Citigroup and Credit Suisse, respectively. 

A theme of the profile is the growth of the practice over the last year. Andrew Weissmann - former chief of the Fraud Section in the US Department of Justice's Criminal Division, general counsel of the FBI, and lead prosecutor in Robert S. Mueller’s Special Counsel’s Office - rejoined the firm as co-chair of the Investigations, Compliance and Defense practice, continuing the firm’s tradition of hiring senior government lawyers. Alongside Mr. Weissmann, the practice has grown in the United States and UK, with the arrival of Douglass A. Mitchell, Amb. David Pressman, Dawn L. Smalls, and Amb. Lee S. Wolosky, as well as the elevation of Robert  J. Dalling to partner. 

A number of other partners are mentioned in the profile, including practice Co-Chairs Anthony S. Barkow, Christine Braamskamp, Gayle E. Littleton, and Erin R. Schrantz; Litigation Department Co-Chair Reid J. Schar; Firm Chair Thomas J. Perrelli; Monitorship Practice Chair Neil M. Barofsky; and Partners David Bitkower.
