TRENTON, NJ — The chief-of-staff to the mayor of New Jersey’s capital city has been charged with attempting to buy drugs.

Trenton Mayor Tony Mack announced yesterday that Paul Sigmund IV had been relieved of his duties “indefinitely” following his arrest Sunday night by city police. Sigmund also was charged with aggravated assault on a police officer.

Sigmund, 46, could not be reached for comment. He joined Mack’s administration in March after state officials urged Mack to hire a chief-of-staff.

Sigmund is a member of a prominent political family. His late mother, Barbara Boggs Sigmund, was a mayor of Princeton and the daughter of former Louisiana Rep. Hale Boggs. His aunt is ABC News commentator Cokie Roberts.
