President Barack Obama has had a lot of firsts in his time in office: first African American president,  first president to establish a healthcare system, first president to sing on national TV.

He'll have another interesting first come Thursday: He'll be the first sitting president to tour a federal prison. 

He spoke on Tuesday to a group of leaders and supporters at the annual NAACP Convention in Philadelphia and talked about prison reform and the dramatic increase in Americans behind bars.

Sarah Wheaton, a White House Reporter for Politico, and Andrew Cohen, editor with the Marshall Project, joined the show to talk about the president's push for sentencing reform
