San Diego ? The estranged wife of disgraced former congressman Randy “Duke” Cunningham will pay $1.6 million in back taxes and penalties for her role in the bribery scandal that landed him in prison, according to a settlement filed Friday.

The federal government sued Nancy Cunningham last year. The settlement means she will not be prosecuted for any charges relating to her husband’s activities.

Duke Cunningham resigned from Congress and was sentenced in March to more than eight years in prison. He admitted last November to accepting $2.4 million in bribes from defense contractors in exchange for government contracts and other favors.
