President Barack Obama has taken to the pages of the Harvard Law Review — which he edited as a student — to defend his record of criminal justice reform.

In an article published Thursday, titled “The President’s Role in Advancing Criminal Justice Reform,” Obama touted his efforts to make the criminal justice system more fair and effective, from the record number of clemency petitions he granted to expanded mentoring of young minority men. He also made the case that major reform is still needed and that the president can play a leading role in driving those changes.
