Matthew Klapper

Matthew Bennett Klapper (Born December 16) is an American attorney who serves as Chief of Staff and Senior Counselor to the Attorney General at the United States Department of Justice. He is among the longest-serving chiefs of staff in the history of the department.

Klapper previously served on the Biden-Harris Transition Team as the "navigator" for the attorney general nominee and met Attorney General Merrick Garland through that work. He has also served in various roles under United States Senator Cory Booker, including as his long-time chief of staff and his 2020 presidential campaign senior advisor. Klapper served for over a decade as a firefighter and emergency medical technician, including over three years in a full-time capacity, and several more as a volunteer. He received recognition for returning to service as an EMT in one of New Jersey's hardest hit counties at the height of COVID-19 when Governor Phil Murphy called upon retired medical and emergency services personnel to return to duty to fill severe staffing shortfalls.
