Subpoenas for union in sale of hosp

SOME OF Mayor de Blasio’s staunchest union supporters have been drawn into the federal probe of his role in the sale of Long Island College Hospital in Brooklyn.

Workers for the powerful health care union SEIU 1199 have received federal subpoenas, The New York Times reported Friday.

David Bates, a spokesman for the union declined to comment when contacted by the Daily News. But as The News first reported Monday, U.S. Attorney Preet Bharara (photo) opened a probe into the 2015 LICH sale — and had already issued a subpoena to State University of New York, the hospital’s previous owner.

The subpoena seeks all contact between the university system and City Hall regarding the sale of the Cobble Hill site dating to Jan. 2, 2014, when de Blasio took office. It also specifies emails and other communication from de Blasio and top aides Tony Shorris, Emma Wolfe, Dominic Williams, Avi Fink and Henry Berger, two sources said.

In addition, Bharara’s office wants all communication from 2013 between SUNY and de Blasio’s campaign and his fund-raiser Ross Offinger, as well as various groups tied to the mayor such as the Campaign For One New York, UPKNYC, and United for Affordable NYC.

A City Hall spokesperson said Friday it had not been contacted by the feds.

“The administration hasn’t been subpoenaed, but we will of course share whatever appropriate information is requested of us during any review of this matter,” the spokesperson said.
