People

Zack Harmon is a partner in the firm’s Special Matters & Government Investigations practice. He has served in leadership roles in the Department of Justice (DOJ) and Federal Bureau of Investigation (FBI), including most recently as FBI Chief of Staff. During the course of his 25-year career, he has led hundreds of investigations across a wide spectrum of issues, industries and geographies. 

Clients ranging from Fortune 100 global corporations to senior company executives and boards rely on Zack to address issues posing enterprise risk.  

As the leader of King & Spalding's national security practice, Zack provides clients with cutting-edge guidance regarding the practical implications of U.S. national security priorities. He helps clients to preempt and respond to nation-state IP theft and data breaches; navigate emerging government requirements concerning cybersecurity and business transactions; and liaise with senior government officials at DOJ, FBI, SEC, State, Treasury, DOD and Congress to address national security concerns of all kinds.

After serving for over 15 years as a leader of King & Spalding's government investigations team, Zack also focuses on government and internal investigations, as well as compliance counseling.  He has served as lead counsel to clients in a wide variety of industries. He has led investigations in over 30 countries and designed global compliance programs for companies operating in numerous industries. Zack also has extensive trial experience, having first-chaired over 25 jury and bench trials in federal and state courts throughout the country.

Zack’s focus on national security dates back to his appointment to the presidential commission that investigated the FBI’s national security and counterintelligence programs in the wake of FBI Special Agent Robert Hanssen’s espionage.  Thereafter, serving as Counsel to U.S. Deputy Attorney General Larry D. Thompson, he played a central leadership role in DOJ’s extensive mission shift following 9/11. He held other roles at DOJ, including as Trial Attorney on the Enron Task Force, Special Assistant U.S. Attorney in the District of Columbia, and prosecutor in the Tax Division of the U.S. Department of Justice.

Before first joining King & Spalding in 1996, Zack clerked for the Honorable William Garwood, United States Court of Appeals for the Fifth Circuit.  Zack retains Secret and Top Secret clearances.
