President Donald Trump announced on June 13, 2026, his intention to name James M. McDonald as the United States Attorney for the Southern District of New York (SDNY). McDonald, a highly regarded litigator and former federal prosecutor, is expected to succeed Jay Clayton, who has been serving in the role since 2025.
McDonald currently serves as a Senior Partner at Sullivan & Cromwell, where he co-heads the firm’s Securities & Commodities Investigations Practice. His private practice has focused on advising major financial institutions and individuals on regulatory enforcement, white-collar criminal defense, and internal investigations.
A Return to Public Service
This appointment marks a return to the Department of Justice (DOJ) for McDonald, who previously served as an Assistant U.S. Attorney in the very district he has now been tapped to lead. During his earlier tenure at the SDNY, he prosecuted a wide array of cases, including white-collar offenses, international narcotics trafficking, and violent crime.
McDonald is perhaps best known for his leadership at the CFTC from 2017 to 2020. As Director of Enforcement, he was responsible for creating specialized task forces focused on digital assets, anti-money laundering, and foreign corruption. His work at the commission was characterized by aggressive enforcement of the Bank Secrecy Act and the prosecution of high-profile "spoofing" cases in the commodities markets.
Legal Pedigree and Market Impact
The nomination of a Sullivan & Cromwell partner underscores the administration's preference for elite legal talent with deep ties to the financial sector. McDonald’s resume includes a clerkship for Chief Justice John G. Roberts, Jr. at the U.S. Supreme Court and service as Deputy Associate Counsel in the White House under George W. Bush.
Market analysts suggest that McDonald’s deep expertise in cryptocurrency and derivatives will likely shape the SDNY’s priorities in the coming years. His previous work at the CFTC involved significant coordination with the Securities and Exchange Commission (SEC) and international regulators, suggesting a collaborative but firm approach to financial market oversight.
The appointment will require confirmation by the U.S. Senate. If confirmed, McDonald will oversee a district that handles many of the nation's most sensitive financial and political prosecutions, maintaining its reputation as the "Sovereign District" of the American legal system.
