From "Mayor de Blasio’s Hired Guns: Private Consultants Help Shape City Hall," New York Times:
Mr.
Rosen [co-founder of BerlinRosen] appears on the mayor’s schedules roughly two dozen times in the
first 17 months of the administration, particularly toward the
beginning. His wife, Debbie Rosen, who had served in the administration
of Mayor Michael R. Bloomberg, was hired last year by the de Blasio
administration, serving as chief of staff at the Office of Management
and Budget.
Earlier
this year, Mr. de Blasio described Mr. Rosen as a close friend who
“doesn’t represent the interests of his clients when he talks to me.”
But
emails obtained by The Times under the state’s Freedom of Information
Law show that Mr. Rosen has represented the interests of his clients in
exchanges with members of the de Blasio administration.
Several of Mr. Rosen’s requests to City Hall concerned invitations for the mayor to attend events for his firm’s clients.
