Many residents of the small town of Guttenberg are calling for their mayor to step down after he and his wife were convicted on extortion and tax charges Tuesday.

Mayor David Delle Donna and his wife Anna, a former town planning board member, were found guilty of using campaign contributions for personal use. They were also convicted of taking bribes for letting code violations slide.

The couple?s conviction comes two weeks after that of former Newark Mayor Sharpe James. The FBI says it is sending a message to corrupt politicians.

"Political corruption is our highest criminal investigative priority,? Weysan Dun of the FBI says. ?It is a crime problem that we will spare no effort and no resources to tackle."The mayor and his wife face up to six years in prison. Their attorney plans to appeal the conviction. The couple is free on bail until sentencing.
