Obama is the first sitting U.S. president to visit a federal prison.

As part of a weeklong focus on inequities in the criminal justice system, President Obama will meet separately Thursday with law enforcement officials and nonviolent drug offenders who are paying their debt to society at the El Reno Federal Correctional Institution, a medium-security prison for male offenders near Oklahoma City.
