John Bencivengo is due to appear Wednesday in U.S. District Court in Trenton.
The former Hamilton Township mayor was convicted last November on extortion, money laundering and bribery-related counts. Bencivengo resigned as mayor of the Mercer County community the day after he was convicted, and now faces several years in prison.
Federal prosecutors said Bencivengo took $12,400 in bribes from a health insurance broker between May and July 2011. In exchange, he promised to use his influence to help the broker keep a health insurance contract with the township's school district.
Bencivengo's lawyer claimed the money was a loan and that his client didn't have the ability to influence school board decisions.
