A spokeswoman for the attorney general declined to comment. A spokesman for the state taxation agency could not be reached for comment late Thursday.
Guy Petrillo, an attorney for Cohen, did not immediately respond to a request for comment.
Underwood’s request was first reported by the New York Times.
Cohen pleaded guilty in federal court Tuesday to eight felonies, acknowledging that he had concealed more than $4 million in income from the IRS. Prosecutors said he had unlawfully avoided more than $1.4 million in federal income taxes.
He faces a recommended sentence of four to five years in jail.
Separately, the New York state taxation agency has also issued a subpoena to Cohen, asking for information related to another state investigation — this one into Trump’s charity, the Donald J. Trump Foundation. Cohen has indicated he may cooperate with that probe.
