ALBANY, N.Y. (CBSNewYork/AP) — A state ethics commission has sent a notice of delinquency to former New York Assembly Speaker Sheldon Silver, seeking information about his outside income.

Silver (D-Manhattan) stepped down as speaker this month after being charged with taking nearly $4 million in kickbacks and payoffs. He has kept his Assembly seat and has said he will be exonerated.

The notice of delinquency was sent this month by the Joint Commission on Public Ethics, which had previously asked Silver to provide more information about private legal work he did in 2011 through 2013. Silver did not comply.

Silver could face a fine of up to $120,000 if he is found to have violated disclosure rules.

His spokesman said Wednesday that Silver believes he followed the law and plans to prove it.

Silver led the Assembly for 21 years before his resignation. Assemblyman Carl Heastie (D-The Bronx) was named to succeed Silver earlier this month.
