The office of New York Governor Andrew Cuomo has hired outside lawyers, including New Jersey’s former top federal prosecutor, to deal with a broad investigation that could lead to Cuomo’s impeachment proceedings.

The Executive Chamber hired Paul Fishman, a partner at Arnold & Porter who served as U.S. Attorney for New Jersey from 2009 to 2017. The law firm said Fishman will be joined by Mitra Hormozi of Walden Macht & Haran. Hormozi is a former executive vice president and general counsel at Revlon, Inc. with long-term connections to Cuomo.
