Gore himself was elected to its board in 1785, when he also became a shareholder. During his time on the board the bank tightened its regulations on loan repayments, a move that improved the stability of its capital. Gore used the bank for most of his personal deposits, but also drew on lines of credit for as much as several thousand dollars.

Gore controversially refused to resign from the state legislature, arguing that the state constitution's prohibitions against holding multiple offices did not apply to federal posts. He eventually resigned the legislative seat under protest because of pressure from his fellow legislators. Gore served as district attorney until 1796. His principal matter of concern was the enforcement of U.S. neutrality with
