I can not find it and don't know how to look it up.
You go to Google and you type in something like this:
new york state legislators felony pension
This asks Google to list first all pages which contain all of those words, if there are any, or failing that, some of them.
You are led to various pages, including this one (the first hit when I tried the search):
Page heading "Restoring Public Trust and Integrity - New York State"
The top story summary has a link to a page:
This page informs the reader (among other things):
1. State Assemblyman David Buchwald (D-Westchester) announced that his bill, which would strip pensions from corrupt officials who commit a felony had passed the Assembly Governmental Operations Committee by a vote of 9 to 4.
2. New York State passed the Public Integrity Reform Act in 2011 to reduce benefits for public officials who abuse their power but it only applied to officials who entered into the state pension system after it became law. This new legislation would amend the State Constitution so that any corrupt official, regardless of when they took office, will know that they risk losing their taxpayer-funded pension.
Whether or not the bill has been passed I do not know.
