 Sotomayor was appointed by Mayor Ed Koch in 1988 as one of the founding members of the New York City Campaign Finance Board , where she served for four years . There she took a vigorous role in the board 's implementation of a voluntary scheme wherein local candidates received public matching funds in exchange for limits on contributions and spending and agreeing to greater financial disclosure . Sotomayor showed no patience with candidates who failed to follow regulations and was more of a stickler for making campaigns follow those regulations than some of the other board members . She joined in rulings that fined , audited , or reprimanded the mayoral campaigns of Koch , David Dinkins , and Rudy Giuliani .
