Narrative Bio

A member of the Commercial Litigation Group, Jim Letten—a 1979 Tulane University law graduate and member of the Louisiana Bar—consults and provides representation on criminal and regulatory investigations by government agencies, as well as civil fraud cases and international trade and regulatory issues, including the establishment of corporate compliance and integrity programs. He previously served 36 years as a prosecutor (31 years with the United States Department of Justice). Before his retirement at the end of 2012, Jim was the longest-serving United States Attorney in the nation and one of only three U.S. Attorneys appointed to the position by successive presidents from different parties. In all, he spent nearly 12 continuous years as the United States Attorney in New Orleans/Southeast Louisiana. Prior to serving as the ranking federal law enforcement official in the District, Jim had distinguished himself as Organized Crime Strike Force Chief and later First Assistant U.S. Attorney.

Jim spent over 30 years prosecuting virtually every type of complex state and federal White Collar, Narcotics and Corruption offense (including extensive experience with RICO prosecutions). He investigated, charged, and tried a broad spectrum of money laundering offenses, including violations of Title 18 US Code Sections 1956 (Laundering) and 1957 (Investment of Illegal Proceeds), as well as Title 31 US Code Section 5324 (Structuring to Evade CTR Reporting Requirements)—all of which contribute to his Anti-Money-Laundering and Bank Secrecy Act compliance skills. Additionally, he was lead prosecutor in a case in which before Congressional enactment of the sting provision of 31 USC 5324 prohibiting structuring, in order to bring federal charges against launderers in an undercover operation, he successfully charged individual violators as “financial institutions” under Title 31.

Over the years Jim has also taught and lectured extensively on the investigation and prosecution of a broad range of Public Corruption offenses, including the RICO, Extortion, Laundering and other federal violations on which former Louisiana Governor Edwin Edwards and co-defendants were convicted in 2000 when Jim led the lengthy and complex investigation and four-month trial. As United States Attorney, Jim served on the Attorney General’s Advisory Committee (AGAC) and co-chaired the AG’s Special Policy Review Working Group on Capital Punishment. He also served on the AGAC Subcommittees on Terrorism and National Security, as well as Environmental Issues.

A military veteran of 20 years in the U.S. Naval Reserve, Jim is a retired Navy Commander, having focused much of his career on foreign counterintelligence (having been variously tasked to Defense Intelligence Agency and Office of Naval Intelligence); and some 13 years as a fully-credentialled NCIS Agent.

Following the devastation of Hurricane Katrina, Jim helped to establish and eventually served as the Director of the National Center for Disaster Fraud. He also received recognition for his leadership from the Attorney General of the United States and due to his anti-corruption expertise, has lectured and has been published in China on the U.S. FCPA and global anti-corruption trends and legislation, on behalf of Tulane, Yale and Zhejiang Province Law Schools. Jim has also provided representation to major American Universities on sensitive issues involving grant compliance and protection of sensitive personal privacy data involving the EU.
