In national security speech last month, Obama said this was the lingering issue that would remain after the other steps that he outlined were taken.
The Pentagon released the identities of the 48 prisoners to the Herald after the paper filed a lawsuit in March under the Freedom of Information Act (FOIA). The paper had the help of Yale Law School students to fight the suit in court.
The identities of the detainees were also sent to the House and Senate Armed Services Committees.
Two of the prisoners on the list have died, leaving 46 remaining detainees being held indefinitely. According to the Herald, those detainees include 26 Yemenis, 12 Afghans, three Saudis, two Kuwaitis, two Libyans, a Kenyan, a Moroccan and a Somali.
