As both liberals and conservatives make a push for criminal justice reform, there are a few Republicans who have staunchly defended the old tough-on-crime mentality—including Senate Judiciary Committee Chairman Chuck Grassley (R-Iowa).

The Obama administration has been trying to woo Grassley over to the reform side—and according to a recent National Journal report, Grassley may in fact be changing his mind on mandatory minimum sentencing reform.

In the past, Grassley slammed the Smarter Sentencing Act, which would reform mandatory minimums, as part of the “leniency industrial complex” and “a weak attempt to defend the indefensible.”

Now, National Journal reports, Grassley may be about to drop bipartisan justice reform legislation, complete with mandatory minimum sentencing reforms.

"It's not as far as I would like, but we are getting somewhere," Sen. Patrick Leahy told NJ.

"It was a long process, and he came in insisting on a different approach and we said, 'All right, let's take your approach and see how close we can come to our goal.' And he has worked in good faith with us and we're close," said Minority Whip Dick Durbin.

Support from Grassley could be enormously important in moving a bill like this forward—and in cementing justice reform as the one issue actually uniting partisans on Capitol Hill.
