After weeks of speculation, Gov. Andrew Cuomo formally nominated Linda Lacewell, his current chief of staff, to become the next superintendent of the state Department of Financial Services, the state’s financial regulatory agency.

Lacewell will replace outgoing Superintendent Maria Vullo, who announced in December that she would be leaving the agency at the end of January. Vullo has not decided what she’s planning to do after leaving the Cuomo administration, which she’s served in for the last three years.
