President Donald Trump announced that he plans to nominate James M. McDonald, a former federal prosecutor and member of his criminal defense team, to lead the powerful U.S. Attorney’s Office for the Southern District of New York. The role is one of the most influential federal prosecutorial positions in the United States.
Trump shared the announcement on Truth Social, saying McDonald would bring “strong results” and work effectively with law enforcement and the judiciary. The nomination will still require approval from the U.S. Senate before it can be finalized.
If confirmed, McDonald would replace Jay Clayton, who has been nominated to serve as the next director of national intelligence. The change is part of a broader reshuffling of key legal and intelligence positions within the administration.
The Southern District of New York is widely regarded as one of the most powerful federal prosecutor offices in the country. It handles major cases involving Wall Street, financial crimes, corruption, cybercrime, and international economic disputes.
McDonald previously worked as a federal prosecutor and later served in private practice at Sullivan & Cromwell, a major international law firm. His work has included cases involving regulatory enforcement, antitrust matters, cryptocurrency, and financial markets.
He also played a role on the legal team that appealed Trump’s 2024 criminal conviction in New York, which involved charges related to falsifying business records in connection with a hush money payment.
The nomination continues a pattern in which Trump has elevated former personal lawyers and legal allies to high-ranking government positions. Several members of his legal circle have already been appointed or nominated to senior roles across the Justice Department and federal judiciary.
Todd Blanche, another member of Trump’s legal defense team, has been selected to serve as attorney general. Other former Trump lawyers have been nominated for federal judicial positions or senior prosecutorial posts in different districts.
McDonald also brings prior government experience beyond his private-sector work. He previously served as director of enforcement at the U.S. Commodity Futures Trading Commission during Trump’s first term. He also worked earlier in his career as an assistant U.S. attorney in the Southern District of New York.
In addition, McDonald has held roles in both the Bush administration and in private legal practice, including clerking for Chief Justice John G. Roberts Jr. at the Supreme Court of the United States.
Supporters of the nomination, including Jay Clayton, have praised McDonald’s legal expertise and ability to handle complex regulatory and financial matters. Clayton previously described him as a sharp legal strategist with strong insight into emerging issues.
In a recent podcast discussion, McDonald highlighted the growing legal challenges surrounding artificial intelligence and automated systems. He noted that regulators are increasingly confronted with questions about accountability when algorithm-driven systems produce unexpected outcomes.
His comments reflect a broader legal debate in the United States over how technology, finance, and enforcement intersect in rapidly evolving industries.
The nomination now moves to the Senate, where McDonald is expected to face scrutiny given the high-profile nature of the Southern District of New York and its importance in federal law enforcement.
