Federal prosecutors issues subpoena in inquiry on Cuomo’s closing of Moreland Commission

Federal prosecutors investigating Gov. Andrew M. Cuomo’s shutdown of an anticorruption commission have subpoenaed the assistant to its former executive director to testify before a grand jury in Manhattan, suggesting that the criminal inquiry has moved to a new stage, people briefed on the matter said on Thursday.

Federal agents served the subpoena on the assistant, Heather Green, on Wednesday morning, appearing at her doorstep before 7 a.m., the people said. Ms. Green, who is not believed to be a target of the inquiry, worked as an executive assistant to the anticorruption panel’s former executive director, Regina Calcaterra, until Mr. Cuomo announced he was disbanding the panel, known as the Moreland Commission, on March 29.

The subpoena, according to two people who have seen it or been briefed on its contents, asked for documents and correspondence, including any communications with Mr. Cuomo and his senior aides. It also directed Ms. Green to appear July 28 to testify before a grand jury in Manhattan, the people said.
