Sentencing for Sister Megan Rice and two other Catholic peace activists is scheduled for Tuesday. They were convicted of sabotage last year after breaking into a nuclear weapons plant in Oak Ridge, Tenn.

The government has recommended sentences of about six to nine years for Rice, Michael Walli and Greg Boertje-Obed. It also is seeking restitution of nearly $53,000. The activists are asking for leniency. They say their actions were symbolic and meant to draw attention to America's stockpile of nuclear weapons, which they call immoral and illegal.

Sentencing is scheduled for 9 a.m. Tuesday at U.S. District Court in Knoxville.
