Upon receiving his Juris Doctor, Spitzer clerked for Judge Robert W. Sweet of the U.S. District Court for the Southern District of New York, then joined the law firm of Paul, Weiss, Rifkind, Wharton & Garrison. He stayed there for less than two years before leaving to join the New York County District Attorney's office.  Spitzer joined the staff of Manhattan District Attorney Robert M. Morgenthau, where he became chief of the labor-racketeering unit and spent six years (1986-1992) pursuing organized crime. Spitzer's biggest case came in 1992, when he led the investigation that ended the Gambino crime family's organized crime control of Manhattan's trucking and garment industries.  Spitzer devised a plan to set up his own sweatshop in the city's garment district, where he turned out shirts, pants and sweaters, and hired 30 laborers. The shop manager eventually got close to the Gambinos, and officials were able to plant a bug in their office. The Gambinos, rather than being charged with extortion - which was hard to prove - were charged with antitrust violations. Joseph and Thomas Gambino, the latter being an extremely high-ranking member, and two other defendants took the deal and avoided jail by pleading guilty, paying $12 million in fines and agreeing to stay out of the business.  Spitzer left the District Attorney's office in 1992 to work at the law firm of Skadden, Arps, Slate, Meagher & Flom. From 1994 to 1998 he worked at the law firm Constantine and Partners on a number of consumer rights and antitrust cases.
