BELVIDERE, N.J. (Warren County) — Warren County Prosecutor Jessica L. Cardone has announced the appointments of her office’s legal leadership team, with two top prosecutors formally sworn into new roles during a ceremony this week.
Michael J. Sweeney was sworn in as first assistant prosecutor, and Naya A. Tsang as executive assistant prosecutor during a ceremonial oath of office held April 22 in the historic courtroom of the Warren County Courthouse. The ceremony was administered by Superior Court Judge H. Matthew Curry.
Prosecutor Cardone said the appointments reflect the direction of her administration and the values of the office.
“These appointments reflect the values we are building upon as an Office. I am proud to have such dedicated and respected professionals beside me as we continue to strengthen this Office, supporting our law enforcement partners, serving victims and pursuing justice for the people of Warren County.”
Sweeney, who will serve in a key leadership role overseeing legal operations and case management, brings more than 30 years of legal experience. His background includes serving as a legal adviser for the New Jersey Department of Health’s Ann Klein Forensic Center, as well as prosecutorial roles in New Jersey and New York, including leadership positions in Hunterdon County and Richmond County, New York.
Tsang, who will help oversee policy development, training and prosecutorial supervision, currently leads the office’s Professional Standards Unit. In that role, she manages internal affairs investigations and supports local law enforcement agencies across Warren County.
Tsang has more than 17 years of experience with the Warren County Prosecutor’s Office and previously served in multiple units, including trial, appellate, domestic violence and Megan’s Law. She began her legal career as an assistant district attorney in Brooklyn, New York.
Officials said the appointments reflect Prosecutor Cardone’s commitment to strong leadership, ethical service and the effective administration of justice for Warren County residents.
