After good-government groups criticized the ethics legislation he signed into law this week, Gov. Andrew Cuomo on Thursday acknowledged more work needed to be done the issue.

Speaking with reporters at the State Fairgrounds outside of Syracuse, Cuomo touted the new disclosure requirements in the measure as a major step forward in regulating shadowy money in politics.

But he also indicated he wanted to do more on the issue after approving the fourth ethics law in the more than five years he has been governor.

“The ethics bill is a major step forward,” Cuomo said. “Is it everything? No. Ethics in many ways is like other activities in life, right? That old line — you can never be too rich, you can never be too thin. Well, you can never be too ethical. So, you get everything done that you can get done. But you stay at it and you work at. More and more disclosure, more trust.”

Cuomo approved what was widely considered to be the ethics bill of the legislative session, a measure designed to address the Citizens United era of super PAC political spending, as well new requirements for lobbyists and consultants.

Good-government advocates have blasted the measure, saying it would unduly impact non-profit organizations who may have a difficult time complying with the law.

At the same time, the ethics watchdogs criticized Cuomo, who proposed the initial measure in June, for not going far enough on reform measures in Albany in the wake of a series of corruption scandals and arrests that have plagued the Legislature.

Both the former Assembly speaker and Senate majority leader were ousted in the last year following corruption convictions that rocked the Capitol.

“Albany certainly had a bad year in terms of trust,” Cuomo said. “They needed an ethics reform so people knew they could trust Albany and this is a great first step.”
