Mintz has further expanded its corporate investigations, enforcement and white collar practices with the arrival of highly recognized trial and investigative lawyer Jason P.W. Halperin. A former Assistant United States Attorney in the Southern District of New York, Mr. Halperin’s practice focuses on white-collar criminal defense, internal investigations, regulatory enforcement and litigation matters. He joins the firm’s New York office from Gibson, Dunn & Crutcher LLP, and will serve as a Member in the national litigation practice.

Mr. Halperin is the second former federal prosecutor to join Mintz’s nationally recognized litigation team in the last several months. In May, the firm announced the addition of David Siegal, who also served as an Assistant United States Attorney in the Southern District of New York. In addition to Mr. Siegal, Mr. Halperin also joins Peter Chavkin, a former special assistant to the head of the Department of Justice’s Civil Division and New York federal prosecutor, who Co-chairs Mintz’s White Collar Defense Practice.

“Jason is a highly accomplished and talented attorney, and we are extremely fortunate to have him join our litigation team. Jason has been successful as a prosecutor in the U.S. Attorney’s office and in private practice where he represented an impressive array of clients in high stakes government and internal investigations, and he further strengthens our ability to serve our clients,” said Bob Bodian, Managing Member of the firm.

Mr. Halperin served in the Southern District of New York from 2004-2015, during which time he conducted 13 federal jury trials and never lost a trial. Throughout his tenure he tried numerous high-profile cases, including the terrorism trial involving four men from Newburgh who were convicted of plotting to blow up synagogues in Riverdale, New York, and a public corruption trial involving a Yonkers City Councilwoman and her political patron who were convicted of conspiracy, mail fraud, wire fraud, bribery, extortion, mortgage fraud, and tax fraud. He also successfully prosecuted three New York State Senators, political aides and developers for white-collar corruption crimes and tax fraud. In addition, he prosecuted a vast array of white-collar fraud cases, including public corruption, bank fraud, wire fraud, mortgage fraud, money laundering, tax evasion, obstruction of justice, and false statement cases.

Mr. Halperin also brings significant experience in international investigations and prosecutions. He has prosecuted both international and domestic terrorism cases as well as national security cases that involve unlawful exports, international sanctions, international money laundering and overseas money transmitting schemes, and require expertise in OFAC, the International Emergency Economic Powers Act, and federal export regulations.

Highly knowledgeable about national and international security, Mr. Halperin has worked with foreign prosecutors, foreign law enforcement, and foreign intelligence agencies, as well as with the U.S. intelligence community. In 2013, he won the Office of the Director of National Intelligence (ODNI)’s Counterintelligence Award for Excellence, the ODNI’s highest nationwide award, for an international counterproliferation investigation. He has further conducted trainings on counterintelligence and public corruption cases with other prosecutors and federal agents from around the country at the U.S. Department of Justice’s National Advocacy Center.

Mr. Halperin has extensive experience practicing before the United States Court of Appeals for the Second Circuit, having briefed and argued numerous cases on appeal. After attending Yale University and the New York University School of Law, Mr. Halperin clerked for the Honorable Ricardo M. Urbina, United States District Judge for the District of Columbia.
