Leon is a partner in Jenner & Block's [Investigations, Compliance, and Defense Practice](https://www.jenner.com/en/capabilities/practices/investigations/investigations-compliance-and-defense), where he advises companies, boards, and executives facing high-stakes government investigations, complex compliance challenges, and corporate criminal exposure. He brings nearly two decades of leadership experience from both the highest ranks of the Department of Justice (DOJ) and the C-Suite of a Fortune 100 company. Glenn served as Chief of the Fraud Section at the DOJ's Criminal Division, directing more than 150 white-collar prosecutors investigating and prosecuting the Department’s most complex white-collar and corporate criminal cases, focusing on cases of national significance that are often transnational in scope. He oversaw major healthcare fraud schemes, securities and commodities fraud, federal procurement fraud, and all Foreign Corrupt Practices Act (FCPA) investigations and prosecutions nationwide, while playing a central role in developing corporate enforcement and compliance priorities. Under his leadership, the Fraud Section achieved an appreciable increase in corporate resolutions in 2024 and tried more cases than in any prior three-year period. He restructured the section's talent development approach and significantly enhanced its use of data analytics in case generation. Glenn's unique perspective combines government enforcement experience with corporate leadership. As Senior Vice President and Chief Ethics and Compliance Officer at Hewlett Packard Enterprise, he oversaw the company's global ethics and compliance program during significant corporate restructuring, leading a multijurisdictional team responsible for compliance strategy, risk assessment, and remediation while reporting regularly to the Audit Committee of the Board of Directors. Earlier in his career, as Assistant Chief and Acting Deputy Chief of the DOJ's Fraud Section, Glenn led high-profile investigations of Fortune 100 corporations involving securities fraud, insider trading, money laundering, and FCPA violations. He spearheaded the LIBOR manipulation investigation, culminating in a $325 million criminal resolution with Rabobank. As an Assistant US Attorney in Washington, DC, Glenn prosecuted federal white-collar crimes and tried approximately 25 jury trials, including securing multiple felony convictions as lead prosecutor in an eight-month RICO conspiracy trial. ## Overview Glenn S.
