The United Federation of Teachers (UFT) most recent campaign finance filings appear to indicate that that the union broke campaign finance laws. The filings show that the union's super PAC paid $370,000 to consultants that are working directly with a number of UFT-endorsed candidates.
According to the New York Daily News:
Independent super PACs can advocate all they wish, but candidates who receive public financing are not supposed to coordinate with a PAC. The rule is intended to bar candidates from pretending to live under spending limits while having a fake outside group spend wildly on their behalf. The UFT surely looks to have done that, while also failing to report robocalls on behalf of Councilman Robert Jackson.
