Winfield pleaded guilty in U.S. District Court in Natchez. He faces up to 10 years at sentencing, scheduled for Nov. 19 before U.S. District Judge David C. Bramlette III.
The plea deal prohibits Winfield from running for elected office in the future or applying to work for any government entity, according to a news release from U.S. Attorney Gregory Davis. He also agreed to forfeit the bribe money.
Winfield, a Democrat, completed his first term as mayor this year and lost his re-election bid.
Winfield’s lawyers did not immediately respond to a phone message Monday.
The criminal complaint in the case says a confidential FBI informant called Winfield on July 17, 2012, to discuss “pre-event disaster contracts” with the city.
It says the two met at a Jackson restaurant the next day, and the informant asked Winfield what it would take to get the contract.
“Winfield responded ‘Ten’ and held up 10 fingers, signifying $10,000,” the complaint says.
