A leading business advocate of criminal justice reform predicted on Wednesday that bipartisan legislation to overhaul sentencing laws will be approved early next year despite differences among Congressional supporters on the bill's final language.

Mark Holden, general counsel and senior vice president at Koch Industries Inc., told an audience at the Council of State Governments Justice Center's annual conference in Washington that he envisions a “floor vote by late January, early February” in the House and Senate on corresponding criminal justice reform bills.

The Senate bill, the Sentencing Reform and Corrections Act of 2015, passed out of the Judiciary Committee in October by a 15-5 vote after winning support from Chairman Chuck Grassley, R-Iowa. Grassley had blocked from committee consideration an earlier bipartisan bill, co-sponsored by Sens. Dick Durbin, D-Illinois, and Mike Lee, R-Utah, that included sweeping reductions in mandatory minimum sentences. Grassley has generally supported such punishments.
