Joseph Giorgianni, one of the closest associates of Trenton Mayor Tony Mack, is accused of operating a prescription drug clearing house out of his restaurant, JoJo's Steakhouse, in Trenton, N.J.
Federal prosecutors say Giorgianni oversaw the operation, where he and eight other people are accused of selling prescription pain pills out of the restaurant.
Giorgianni and one of the eight other suspects, Eugene Brown -- both ex-cons, according to U.S. Attorney Paul Fishman -- were also charged with possessing firearms illegally.
Giorgianni was arrested at his home on Monday morning by FBI agents. The government says it has been investigating Giorgianni and Trenton Mayor Tony Mack for the better part of two years for their alleged roles in a political corruption scheme.
The mayor, Giorgianni and the mayor's brother, Rafael Mack, are all charged with conspiring to solicit and accept more than $100,000 in bribes.
