Matthew J. Cannon has more than two decades of criminal and civil litigation experience. He has served as the First Chair in numerous federal jury trials and has combined his courtroom skills, his experience as a federal prosecutor with the Department of Justice (DOJ), and his wide-ranging civil litigation skills into a practice that combines anti-corruption compliance work and litigation.

He also assists companies with implementing and assessing anti-corruption compliance programs throughout the world, including programs focused on the Foreign Corrupt Practices Act (FCPA) and the U.K. Bribery Act.
Matt’s criminal and civil investigations and litigation experience includes handling matters related to the False Claims Act (with an emphasis on representing financial institutions, defense contractors and health care providers) as well as matters involving DOJ and SEC FCPA investigations, antitrust matters, ITAR, criminal and civil environmental investigations and litigation, class action securities fraud litigation, derivative and corporate governance breach of fiduciary duty matters, and multi-state attorney general investigations involving cybersecurity breaches.

Prior to joining Greenberg Traurig, Matt served as a federal prosecutor for more than seven years. During his tenure with the government, he served as both the Supervisory AUSA for the Headquarters Office of the Central District of Illinois and was the Lead Prosecutor for the LOGCAP Working Group—a group that prosecuted warzone corruption matters related to the multibillion-dollar LOGCAP III and IV prime contracts awarded to private contractors to provide logistical support to the U.S. Army in relation to the military conflicts in Iraq, Kuwait and Afghanistan. The LOGCAP Working Group had numerous prosecutions and investigations involving bribes, kickbacks, Major Fraud Act, and civil False Claims Act matters, including qui tams.

As a federal prosecutor, Matt supervised public corruption cases and health care fraud cases in addition to handling prosecutions and investigations in the areas of procurement fraud, wire and mail fraud, money laundering, securities fraud, FCPA, ITAR, Clean Water Act environmental matters, and other white collar matters.
