Michael R. Sherwin provides ultra-high-net-worth individuals and institutional clients strategic advice on international government investigations throughout the Americas, Middle East and Asia. Mr. Sherwin has extensive experience working with prosecutors, investigators and intelligence agencies from these regions on collaborative, long-term corporate fraud, commodities and tax fraud, digital currency and national security matters.

Before joining Kobre & Kim, Mr. Sherwin most recently served as the Acting United States Attorney for the District of Columbia, where he supervised the largest federal prosecutor office in the United States. Under Mr. Sherwin's leadership, his office brought several historic cases, including the largest seizure of illicit Iranian petroleum in U.S. history; the U.S. Department of Justice’s (DOJ) first seizure of illicit digital currency linked to al-Qaida and other designated terrorist groups; and the filing of criminal charges against Libyan national Abu Agela Masud, the alleged bomb-maker who constructed the explosive device that destroyed Pan AM 103 in December 1988, killing 270 people over Lockerbie, Scotland. During Mr. Sherwin's last assignment for the DOJ, he served as the chief prosecutor for all criminal cases related to the Washington, DC Capitol riots of January 6, 2021 – under his supervision, more than 400 criminal cases were filed and over 500 search warrants were executed throughout the United States in less than 10 weeks.

Prior to becoming Acting U.S. Attorney, Mr. Sherwin was an Associate Deputy Attorney General, where he advised Attorney General William Barr and Deputy Attorney General Jeffrey Rosen on national security matters. During that time, Mr. Sherwin worked closely with the National Security Council and provided DOJ leadership advice on sensitive counterintelligence and counterterrorism matters, to include work on various complicated Foreign Intelligence Surveillance Act (FISA) and Committee on Foreign Investment in the United States (CFIUS) cases.

Before Mr. Sherwin's duties in Washington, DC, he served as an Assistant United States Attorney in the Southern District of Florida for 12 years. From 2008 to 2010, Mr. Sherwin did extensive work in South and Central America, where he prosecuted numerous drug cartels and kingpins on wide-scale money laundering and narcotics/weapons trafficking cases. During that time Mr. Sherwin was the lead prosecutor in the conviction of Sigifredo Maya, a top member of the Medellín Cartel and close associate of Pablo Escobar and Carlos Lehder.

For six years, until 2018, Mr. Sherwin prosecuted securities and commodities fraud, tax fraud and multiple Foreign Corrupt Practices Act (FCPA) cases in the Economic Crimes Section. In 2016, he became Chief of the Health Care Fraud Section, supervising the largest Health Care Fraud Strike Force in the United States. Under Mr. Sherwin's leadership, his section led the nation in all federal health care fraud indictments, trials and asset forfeitures from 2016-2018.

In 2018, Mr. Sherwin joined the National Security Section, where he prosecuted counterintelligence and terrorism cases, specializing in economic espionage and state-sanctioned theft of trade secrets and assets/digital currency.

In addition to his work in Miami, in 2011 Mr. Sherwin was chosen by Attorney General Eric Holder to serve a special detail for the U.S. Department of State in Bagram, Afghanistan, where he assisted the Afghanistan Attorney General's Office in more than 120 primary court terrorism trials and 250 appellate cases before a specially convened Afghan judicial tribunal. These cases focused on prosecuting top-tier Taliban and al-Qaida explosives engineers, suicide-bomb recruiters and terrorism financiers.

Prior to becoming an attorney, Mr. Sherwin was an officer in the United States Navy from 1999 to 2004, serving both afloat in the Persian Gulf and Mediterranean Sea, and afoot throughout the Middle East and Europe.
