The first Committee of Safety of the Province of New Jersey was elected on 17 Aug 1775 by the Provincial Congress meeting in Trenton and included Hendrick Fisher, Samuel Tucker, Isaac Pearson, John Hart, Jonathan D. Sergeant, Azariah Dunham, Peter Schenck, Enos Kelsey, Joseph Borden, Frederick Frelinghuysen, and John Schurman. It served during the recess of the Congress in August–September 1775. No minutes of its proceedings are extant; only a small number of resolutions survive.

The second Committee of Safety was elected at a session of the Provincial Congress in Trenton on 28 Oct 1775 and included the President of the Congress, Samuel Tucker, and the Vice President, Hendrick Fisher. The Committee appears not to have met during the remainder of 1775. An announcement dated 18 Dec 1775 and signed by Tucker called for the Committee to meet in Princeton on 9 Jan 1776. It met on that day but adjourned for lack of a quorum, and reconvened on 10 Jan 1776, when Tucker, Fisher, and other members were present. The surviving minutes contain no record of the election of a president; it appears that Tucker served in that capacity ex officio as President of the Congress. On 12 Jan 1776, the Committee of Safety called for the next session of the Provincial Congress to convene on 31 Jan 1776 and adjourned on the following day.

The journal of the Provincial Congress held in New Brunswick between 31 Jan 1776 and 2 Mar 1776 does not record the election of a new Committee of Safety. Nevertheless, the Committee met in March, April, and May 1776, as evidenced by resolutions signed by Tucker as President.
