WASHINGTON, United States鈥擯resident Barack Obama presented a long-shot plan Tuesday to shutter the Guantanamo Bay detention center, hoping to fulfill an elusive campaign promise before he leaves office next year.
Describing the jail as a stain on America鈥檚 reputation and a catalyst for jihadists, Obama said 鈥淚 don鈥檛 want to pass this problem on to the next president.鈥�
鈥淔or many years, it鈥檚 been clear that the detention facility at Guantanamo Bay does not advance our national security. It undermines it,鈥� Obama said from the Roosevelt Room.
He outlined a $290-$475 million plan to move the 91 remaining detainees abroad and to one of 13 possible鈥攗nnamed鈥攆acilities in the United States.
Obama has tried for almost eight years to close the jail, but has been thwarted by Congress, his own Department of Defense and some in his own party.

As a candidate and as president, Obama has argued that the indefinite detention without trial of Guantanamo inmates harms America鈥檚 image and makes it less safe.
鈥淚t undermines our standing in the world,鈥� he said. 鈥淭his is about closing a chapter in our history.鈥�
Lawmakers in the Republican-controlled Congress have blocked the most obvious path to closing the facility, banning the transfer of detainees to the United States, and there was little prospect of Republicans changing tack in the run-up to the November presidential election.
House Speaker Paul Ryan immediately rejected the proposal, saying: 鈥淧resident Obama has yet to convince the American people that moving Guantanamo terrorists to our homeland is smart or safe.鈥�
鈥淚t is against the law, and it will stay against the law, to transfer terrorist detainees to American soil. We will not jeopardize our national security over a campaign promise.鈥�
Obama appealed for the closure plan to be given 鈥渁 fair hearing, even in an election year.鈥�
But Republican Senator and presidential candidate Marco Rubio doubled down in opposing it, promising to increase the Guantanamo population if elected.
鈥淣ot only are we not going to close Guantanamo鈥攚hen I am president, if we capture a terrorist alive鈥� they are going to Guantanamo and we are going to find out everything they know,鈥� he said.
Obama also has faced opposition from within his own administration, with the Pentagon accused of slow-pedaling transfers and overstating closure costs.
The president could still try to force the closure through an executive order, but such a move would expose him to accusations of ruling by decree.
鈥楧angerous precedent鈥�
The Guantanamo Bay closure plan, which took months to produce, offers no specifics on where a US facility would be, but military officials have previously listed Fort Leavenworth, Kansas or the US Navy brig in Charleston, South Carolina among the possible destinations for inmates.
Those locations, however, face objections from local politicians.
The US leader has long argued that many Guantanamo prisoners should be transferred overseas and some should be tried by military courts.
A small number鈥攖hose deemed too dangerous to release but too difficult to prosecute鈥攚ould be held in the United States.
Human rights groups worry this would only extend detentions without trial and create a 鈥淕uantanamo North.鈥�
鈥淭he possibility of a new, parallel system of lifelong incarceration inside the United States without charge would set a dangerous precedent,鈥� Amnesty International said in a statement.
鈥淚f successfully mounted, it would be a devastating blow to basic principles of criminal justice.鈥�
The plan says a US facility would save money over time. It currently costs about $455 million each year to run Guantanamo, and a US site would reduce that amount by up to $180 million.
Most of the savings would come from a decrease in the number of troops guarding the reduced population on the US mainland, although it could cost as much as $475 million in one-time expenses to move the men and build or update a facility to hold them.
Efforts to transfer prisoners overseas have been stymied by unrest in Yemen鈥攁 likely destination for many鈥攁nd by recidivism among those already released.
鈥楨nemy combatants鈥�
Still, Defense Secretary Ashton Carter has in recent weeks signed off on a flurry of transfers, and last month, the prison鈥檚 population dropped below 100 for the first time.
Today, 91 inmates remain. Of them, 35 have been approved for release. The rest face ongoing, indefinite detention.
Perhaps the most notorious prisoner is Khalid Sheikh Mohammed, who along with four co-defendants is charged with plotting the September 11, 2001 attacks.
The Guantanamo Bay military prison was opened in January 2002 on a US naval base on a coastal spit of land in southeastern Cuba, leased from Havana under a treaty dating back to 1903.

It was set up after the 9/11 attacks under the administration of then-president George W. Bush to deal with prisoners who were termed 鈥渆nemy combatants鈥� and denied many US legal rights.
The plan to close the prison has no bearing on the future of the US naval base itself, which is home to about 5,000 people.
