S. Michael Palermo was a close friend and top aide to Fumo. Fumo, a Philadelphia Democrat, is serving a 55-month sentence for defrauding the senate and two nonprofits of several million dollars.
The 69-year-old Palermo is likely to get five years probation under terms of a plea he entered Wednesday.
Prosecutors say there's no evidence he did any work for the $150-an-hour transportation consulting contracts. Palermo says he did some work but nothing close to the 2,000 hours for which he was paid.
A judge set sentencing for Jan. 22.
Defense lawyer Robert Scandone declined comment.
