In July, the White House announced it is finalizing the draft plan to close the detention facility at Guantanamo Bay.
The Obama administration has discussed plans to transfer the remaining Guantanamo detainees to prisons in US states such as South Carolina and Kansas, but some Congressmen have voiced concern over relocating the detainees to the United States.
On Monday, Defense Department spokesman Jeff Davis confirmed that the closure plan will be submitted "soon."
"The president’s [Barack Obama's] goal remains to close the detention facility there and to end this chapter in our history," Davis said as quoted by Stars and Stripes.
In 2009, President Obama pledged to close the notorious detention center amid mounting concern about human rights abuses committed by US personnel against detainees.
White House Press Secretary Josh Earnest said last week that President Obama could close the Guantanamo detention center by using his executive authority if the US Congress does not cooperate on the issue.
At present, 112 detainees remain at the Guantanamo Bay detention facility, 52 of whom are cleared to be transferred abroad, according advocacy group Human Rights First.
