Jonathan S. Kolodner’s practice focuses on white-collar criminal enforcement and regulatory matters as well as complex commercial litigation.

He represents clients in investigations involving a range of misconduct, including foreign corruption, fraud, insider trading, money laundering, and antitrust offenses. He also advises companies on cybersecurity and data privacy issues, and counsels clients on best practices for anti-corruption and cyber-related compliance programs.

Before joining Cleary Gottlieb, Jonathan was a prosecutor with the U.S. Attorney’s Office for the Southern District of New York from 2000 to 2012, where he served in numerous leadership positions and oversaw some of the highest-profile investigations and prosecutions in the country. He served as Acting Chief of the Criminal Division from October 2011 through January 2012. In that role, he supervised the Office’s more than 160 prosecutors in various matters including securities fraud, public corruption, cybercrime, terrorism and violent crimes.

Prior to that, Jonathan spent several years as the Chief of the Complex Frauds Unit. In this capacity, he oversaw 20 senior prosecutors investigating sophisticated, large-scale white-collar crimes ranging from financial and investment matters to Foreign Corrupt Practices Act (FCPA) violations and computer and intellectual property offenses like hacking, theft of trade secrets and other cybercrimes. In addition, from 2006 to 2008, Jonathan was a Deputy Chief of Criminal Appeals, where he oversaw dozens of appellate matters and handled numerous arguments before the U.S. Court of Appeals for the Second Circuit.

Jonathan also spent four years as an Assistant U.S. Attorney in the Organized Crime and Terrorism Unit and has represented the United States in more than 12 jury trials. In 2008, he was awarded the U.S. Department of Justice’s Director’s Award for Superior Performance in connection with his prosecution of over 30 members and associates of the Genovese organized crime family.

Jonathan joined the firm as counsel in 2012 and became a partner in 2014.
