Prosecutors asked a federal judge on Thursday to sentence a former kosher slaughterhouse executive to 25 years in prison, less than the life sentence they have said they were entitled to request.

Former Agriprocessors Inc. manager Sholom Rubashkin, who was convicted of 86 counts of financial fraud in November, gave a tearful, halting speech at the end of his sentencing hearing in U.S. District Court in Cedar Rapids, Iowa. He was charged following a May 2008 immigration raid at the former Agriprocessors slaughterhouse, where 389 workers were arrested on immigration charges.
