Sean M. Thornton is a counsel in Skadden’s Financial Institutions Regulation and Enforcement Group. He served from 2005 to 2012 as chief counsel of the U.S. Department of the Treasury’s Office of Foreign Assets Control (OFAC), where he helped develop and implement the expanding legal framework for U.S. economic sanctions with respect to Iran and played a leading role in a series of landmark settlements with international banks for alleged violations of U.S. sanctions. Mr. Thornton also has advised senior officials in the Department of the Treasury, Department of Justice, Department State and the White House in a wide range of other financial enforcement and regulatory matters, including anti-money laundering (AML), national security litigation and issues relating to the Committee on Foreign Investment in the United States (CFIUS).

Mr. Thornton’s practice focuses on the shifting laws and policies underlying U.S. economic sanctions, including interpretation of new legislation and on AML requirements. His experience includes:

  • Representing clients in complex sanctions and AML investigations, including conducting internal reviews and negotiations with the Department of the Treasury, Department of Justice and New York authorities.
  • Advising clients on economic sanctions issues in high-profile cross-border transactions.
  • Conducting assessments of clients’ AML programs, including an intensive on-site AML review of the foreign-exchange business of a large Latin American bank.
  • Securing licenses and other regulatory approvals when needed.
  • Representing companies and individuals that have been sanctioned by U.S. authorities, helping the clients identify and address the reasons for the sanctions, and advocating on their behalf before relevant U.S. agencies.
