As state lawmakers seek to cap or restrict outside income, Bronx Sen. Jeff Klein will divest himself entirely from his private practice law firm.

“I already told my partners I won’t handle anymore cases, see any more clients, not get any income at all from the firm and remove my name from the sign and the website,” Klein told NY1’s Zack Fink.

Klein, the leader of the Independent Democratic Conference, reported earning between $75,000 and $100,000 in “guaranteed payments” from the firm, Klein Calderoni & Santucci, in a financial disclosure form filed with the Joint Commission on Public Ethics.

Klein reported earning less than $1,000 in interest income from the firm. He reported earning the same range from teaching as an adjunct professor at Mercy College.

“We have no business before the state — either myself or my partners,” Klein said, adding the firm works predominantly on estates and wills.

He will continue to work on pro bono cases, but is dropping paid legal work, Klein said.

His divestiture from the firm comes after the arrest of now former Assembly Speaker Sheldon Silver, who is facing charges that he masked referrals through his law practice as bribes and kickbacks, earning millions of dollars over the last decade.

Silver has subsequently taken a leave of absence from his firm, Weitz & Luxenberg.

Meanwhile, Senate Majority Leader Dean Skelos is reportedly under investigation over his own outside income. Skelos, who is of counsel at the firm Ruskin Moscou Faltischek, reported earning between $150,000 and $250,000.

Klein said his move to end his own outside income voluntarily represents a “clean break.”

“During this crisis we need to win back the voters’ trust,” Klein said. “I think the way we do this is to not have any potential conflicts at all moving forward. I think this is sort of a clarion call for all. If you want to earn outside income, you shouldn’t be in public service.”

Gov. Andrew Cuomo is pushing an outside income disclosure measure this session that would also force lawmakers to reveal their outside clients, as well as restrict them from having clients who have business before the state.

Assembly Speaker Carl Heastie, Silver’s successor, is exploring ways of capping outside income from state lawmakers in addition to the creation of an ethics and compliance office.

While also backing new restrictions on outside income, Klein said he’s supporting a “full-blown” overhaul of the legislative per diem system.
