David D'Amiano, a key McGreevey fund-raiser, was ultimately sentenced to two years in prison for extorting $40,000 from a farmer, Mark Halper, a Middlesex County landowner cooperating with investigators. In the 47-page indictment, there are repeated references to the involvement of "State Official 1," later revealed to be McGreevey. In a conversation with Halper, McGreevey used the word "Machiavelli," the code arranged by D'Amiano intended to assure the farmer that his $40,000 campaign contribution would get him preferential treatment in a dispute over his land.
