and Hewlett Packard Enterprise Chief
Compliance Officer, Joins Jenner & Block in
Washington, DC
News
January 15, 2026

WASHINGTON, DC – January 15, 2026: Jenner & Block is pleased to announce that Glenn Leon
has joined as a partner in its Washington, DC, office, where he will play a key role in the
Investigations, Compliance, and Defense Practice.

Glenn joins Jenner & Block following service as Chief of the Criminal Division's Fraud Section at the
US Department of Justice (DOJ). In this role, he oversaw the nation's most significant corporate
criminal investigations, including, healthcare fraud, commodities, securities, procurement fraud and
Foreign Corrupt Practices Act (FCPA) enforcement. Prior to his tenure as Fraud Section Chief, Glenn
served as Senior Vice President and Chief Ethics and Compliance Officer at Hewlett Packard
Enterprise.

"Glenn is one of the most accomplished white-collar lawyers to emerge from DOJ in recent years,"
said Co-Managing Partners Ishan Bhabha and Randy Mehrberg. "His experience leading the Fraud
Section gives exceptional insight into DOJ decision-making and enforcement priorities. Combined
with his years as Chief Compliance Officer for a Fortune 100 company, Glenn brings a rare skill set
merging the government's perspective and the boardroom's strategic mindset."

While at Hewlett Packard, Glenn chaired the Ethics & Compliance Committee, providing strategic
legal counsel across a complex portfolio that included anti-corruption and FCPA compliance,
securities and accounting fraud prevention, export controls, data privacy, mergers and acquisitions,
and emerging areas such as Environmental, Social, and Governance (ESG) and artificial intelligence
governance. Glenn directed the company's responses to investigations and inquiries from DOJ, the
Securities and Exchange Commission, and criminal and civil authorities across Asia, Europe, and
Latin America, while overseeing all internal investigations relating to alleged ethical and legal
violations and implementing remedial actions that strengthened the company's compliance culture.

Before joining the private sector, Glenn served as Assistant Chief and Acting Deputy Chief of DOJ's
Fraud Section, where he led high-profile investigations of Fortune 500 corporations and financial
institutions involving securities and commodities fraud, insider trading, bank and mortgage fraud,
money laundering, government procurement fraud, TARP fraud, and FCPA violations. Notably, Glenn
spearheaded the investigation into the manipulation of LIBOR and other benchmark interest rates by
global financial institutions, culminating in a $325 million criminal resolution with Rabobank that is
viewed as a significant precedent in market manipulation enforcement.

"Glenn's DOJ experience combined with board-level in-house compliance leadership positions him
as a trusted advisor for companies navigating today's enforcement landscape," said David Bitkower,
Co-Chair of the Investigations, Compliance, and Defense Practice. "He brings deep insight into
evolving enforcement priorities, risk assessment, and program design. His addition expands the
existing industry-leading capabilities at Jenner & Block to serve clients not just in crisis, but in
building resilient compliance programs that prevent problems before they start.

Early in his career, Glenn served for more than a decade in the US Attorney's Office for the District
of Columbia, where he prosecuted complex federal white-collar crimes including securities fraud,
public corruption, money laundering, and computer hacking across multiple sections. Among his
notable achievements, he secured multiple felony convictions as lead prosecutor in an eight-month
RICO conspiracy trial involving six defendants and more than 150 witnesses. Over the course of his
tenure, Glenn tried approximately 25 jury trials and conducted scores of grand jury investigations,
earning numerous recognitions including the DOJ Director's Award for Superior Performance.

"The firm's reputation for excellence in high-stakes matters and its collaborative culture make it an
ideal platform to help clients navigate investigations, compliance challenges, and the evolving
enforcement landscape," said Glenn. "Jenner & Block's unique combination of talent in the ICD
Practice and across numerous industry and specialist groups allows them to provide clients with
practical guidance in their most sensitive and consequential matters. I look forward to partnering
with this exceptional team to deliver strategic, practical advice to companies and their leaders."

Glenn holds a JD from New York University School of Law and a BA from Brandeis University.
