A guard walks into the Guantanamo Bay Detention Center, also known as "Gitmo", a maximum security detention center at the U.S. Naval Station at Guantanamo Bay, Cuba on Oct. 22, 2016.
The U.S. military's Joint Task Force Guantanamo is still holding 60 detainees at the prison, down from a previous total of 780, including 20 cleared for release.
On his second day in office in 2008 President Obama issued an executive order to close the prison, which has failed because of political opposition in the U.S. Congress, mostly from Republicans who argue that they won't jeopardize national security over a campaign promise.

The detention center was opened in January 2002 to hold foreign fighters suspected of links to the Taliban or the al-Qaida terrorist organization

Obama said his administration was still working diligently to shrink the prisoner population and that in doing so he hopes the American people will ask about the expense of maintaining a facility that he believes isn't necessary for their safety and security.

"I continue to believe that Guantanamo is a recruitment tool for terrorist organizations, that it clouds and sours some of the counter-terrorism cooperation we need to engage in," Obama said. Yet Republican White House hopeful Donald Trump has called for expansion of the prison.
