President Obama on Tuesday presented the four-point plan that he has given Congress to close the U.S. detention center at Guantanamo Bay, Cuba, that includes releasing more detainees and transferring the most dangerous of them to U.S. soil

The president presented the plan in his last months of office, in perhaps a final effort to fulfill his 2008 campaign promise.

The plan for the 91 remaining detainees includes:

-- The “careful” transfer of 35 detainees to overseas countries

-- Accelerating the review process for the roughly 56 remaining detainees to see whether they’re eligible for transfer

-- Using “all of the legal tools” available to the U.S. to resolve the cases of detainees in the commission process.

-- Work with Congress to pick a transfer location on U.S. soil

Obama presented the plan as an effort to bolster U.S. security, maintain American values and save money.

“We can improve our security, uphold our highest values around the world and save Americans money in the process,” Obama said.

The facility, on a U.S. Naval base in Cuba, was opened in January 2002, in the aftermath of the 9/11 attacks, to get suspected terrorists off the battlefield.

The Pentagon has recently tried to convince lawmakers to close the detention center with a draft plan to move nearly 60 detainees to a facility on the U.S. mainland that would cost as much as $475 million to build but could save roughly $180 million in aual operating costs.

Closure plans face tough opposition in Congress, which has passed legislation baing any effort to move detainees to the U.S.

Texas GOP Rep. Mac Thoberry, chairman of House Armed Services Committee, is declining to comment on the plan until he finishes his review of it Tuesday moing. But he has previously told Obama that Congress has made clear what must be in such a plan.

However, a committee aide told Fox News on Tuesday that the administration plan is “not compliant."

New Hampshire GOP Sen. Kelly Ayotte said: "While the administration asserts that transferring detainees and closing Guantanamo is in America's national security interests, they refuse to level with the American people regarding the terrorist activities and affiliations of the detainees who remain at Guantanamo."

The U.S. officials say the plan to be aounced Tuesday considers 13 U.S. locations -- seven prison facilities in Colorado, South Carolina and Kansas already proposed and six other locations on military bases.

They also say the plan doesn't recommend a preferred site and that cost estimates are just a starting point for negotiations with Congress.

It’s unclear whether the plan addresses what to do with any top-members of the Islamic State terror groups if they have been captured on the battlefield.

According to the officials, the U.S. facilities would cost $265 million to $305 million to operate each year. The aual operating cost for Guantanamo is $445 million, but the officials said the Cuba detention center will need about $225 million in repairs and construction costs for continued use.

They said a facility will cost $290 million to $475 million to build, depending on the location.

Congress has been demanding the Guantanamo plan for months, and members representing South Carolina, Kansas and Colorado have voiced opposition to housing the detainees in their states.

Those members and others in the GOP-controlled Congress argue that such a facility poses a national security risk, particularly a terror attack.

The administration is currently prohibited by law from moving the detainees to the United States.

The long-ruing dispute has taken on added intensity now because the White House has launched a final push to close the prison before Obama leaves office.

Beyond cost conces, supporters of closing Guantanamo argue that holding suspected terrorists indefinitely without charges or trial further inspires militant groups and alienates U.S. allies.

In addition to having security conces, opponents say changing the detention center's ZIP code won't change those world perceptions.

There are currently 91 detainees at Guantanamo Bay. Of those, 35 are expected to be transferred out by this summer.

At its peak in 2003, Guantanamo held nearly 680 detainees, and there were about 245 when Obama took office.
