Katten Adds Former Federal Prosecutor Michael M. Rosensaft to Litigation Practice

Firm News | September 13, 2012

(NEW YORK) Katten Muchin Rosenman LLP announced today the hiring of Michael M. Rosensaft, who joins the firm’s Litigation Practice as a partner. Rosensaft represents businesses and individuals in white collar criminal and regulatory enforcement matters, corporate internal investigations, and complex civil litigation with an emphasis on insurance and health care fraud litigation.

“With the addition of Michael Rosensaft, we are fortunate to not only have on board a great trial attorney, but one who also has broad experience in all aspects of litigation, from the investigation stage to trial and appeal,” said Vincent A. F. Sergi, Katten’s national managing partner.

Rosensaft most recently served as an Assistant United States Attorney for the Southern District of New York, where he investigated and prosecuted criminal cases involving terrorism, international money laundering, export violations, bribery of foreign officials, narcotics trafficking, RICO/organized crime, murder, bank and wire fraud and computer crimes.

During his time as a federal prosecutor, Rosensaft worked closely with the Federal Bureau of Investigation, the Internal Revenue Service, the Office of Foreign Assets Control and the State Department. His work also extended internationally as he coordinated with law enforcement and government officials in other countries.

Rosensaft worked extensively with the United Nations and prosecutors in Guatemala to investigate former Guatemalan President Alfonso Portillo for money laundering, ultimately leading to his indictment, which was unsealed on January 25, 2010. Among Rosensaft’s other notable cases at the United States Attorney's Office were the successful prosecution of Frank Ma and his organization, dubbed by The New York Times as the “last of the Asian godfathers”; the prosecution of Afghani drug kingpin Haji Juma Khan, who was indicted for financing terrorist activities; and the investigation and prosecution of individuals attempting to bribe members of the Government of Liberia in order to use Liberia as a transshipment point for narcotics.

Rosensaft has served as law clerk to the Honorable Jane R. Roth of the United States Court of Appeals for the Third Circuit. He received his JD from the University of Pennsylvania Law School and his BA from Johns Hopkins University.

Katten’s White Collar Criminal and Civil Litigation Practice comprises highly respected defense lawyers and former federal prosecutors with broad investigative, trial and appellate experience. They regularly conduct internal corporate investigations, defend companies and individuals in grand jury investigations as well as civil and criminal government and regulatory actions, and civilly prosecute racketeering cases aimed at organized crime and other fraudulent activity on behalf of insurance companies. The firm also helps organizations implement corporate detection and compliance programs.
