VIDEO: Historic first-ever presidential visit to penal facility

President Barack Obama got a first-hand look at the nation's criminal justice system Thursday, touring a federal prison and meeting with incarcerated men.

After peering into a sterile prison cell, he said the nation needs to reconsider the way crime is controlled and prisoners are rehabilitated.

Obama, who has vowed to make criminal justice reform a centrepiece of his closing months in office, said he also felt a kinship with some of the young inmates.

The White House said he was the first sitting president to see the inside of a federal prison.
