Jay Clayton is the United States Attorney for the Southern District of New York. Mr. Clayton assumed that role in August 2025, having previously served as Interim U.S. Attorney beginning in April 2025. Since taking office, Mr. Clayton has prioritized the safety and interests of New Yorkers and the millions who visit the city and region each year.  His prosecutorial focus includes gun violence, gang activity, drug trafficking (including operations enabled by cartels and foreign governments), hate crimes, sex trafficking, child exploitation, national security threats, cyberattacks and cyber-enabled fraud, securities and corporate fraud, and money laundering.
  
Mr. Clayton brings extensive experience from both the public and private sectors to the Office.  He was Chairman of the U.S. Securities and Exchange Commission (SEC) from May 2017 to December 2020.

He frequently testified before Congress on issues such as improving market integrity and efficiency, digital asset regulation, cybersecurity, retail and retirement investor interests, COVID-19-related regulatory responses, and U.S.-China economic interdependence.

Following his tenure at the SEC, Mr. Clayton served as Chairman of Apollo Global Management and returned to Sullivan & Cromwell LLP as Of Counsel and Senior Policy Advisor.  He also served on the board of the American Express Company and held various other advisory and oversight roles in both the public and private sectors.
