The sister of Assistant Senate Majority Leader Andre Cushing III has filed an ethics commission complaint against him, a week after filing a lawsuit against the Newport Republican alleging he fraudulently siphoned off assets from a family corporation. In the ethics complaint, Laura Cushing McIntyre of Hermon asks Maine’s ethics commission – which enforces state campaign finance rules – to investigate her brother over possibly improper financial transfers among Cushing, his leadership political action committee, his campaign and a corporation that she says he controls, New England Forest Products. “The ethics committee is there to make sure all candidates are properly managing the funds they receive,” McIntyre told the Portland Press Herald on Friday, adding that she first raised questions with the commission about one of these payments in August 2015 but that it was not acted upon.
