UPDATE: Obama made a stern declaration Tuesday morning in Washington, saying that he is proposing to “once and for all” shut down the detention center in Guantanamo Bay, Cuba. The prisoners still being detained would be shipped to a facility in the United States.

But where will this new facility be? POTUS didn’t say.

But he did say this:

“I don’t want to pass this problem on to the next president, whoever it is. Are we going to let this linger on for another 15 years? Keeping this facility open is contrary to our values. It undermines our standing in the world. It is viewed as a stain on our broader record of upholding the highest standards of rule of law.”

More from the Chicago Tribune on the proposal and/or future plan:

U.S. officials say the plan considers, but does not name, 13 different locations in the U.S., including seven existing prison facilities in Colorado, South Carolina and Kansas, as well as six other locations on current military bases. They say the plan doesn’t recommend a preferred site and the cost estimates are meant to provide a starting point for a conversation with Congress.

The seven facilities reviewed by a Pentagon assessment team last year were: the U.S. Disciplinary Barracks and Midwest Joint Regional Corrections Facility at Leavenworth, Kansas; the Consolidated Naval Brig, Charleston, South Carolina; the Federal Correctional Complex, which includes the medium, maximum and supermax facilities in Florence, Colorado; and the Colorado State Penitentiary II in Canon City, Colorado, also known as the Centennial Correctional Facility.

According to the officials, the U.S. facilities would cost between $265 million and $305 million to operate each year. The annual 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 if it continues to be used.

They said it will cost between $290 million and $475 million for construction at the various U.S. sites, depending on the location. Some of the more expensive sites are on the military bases, which would need more construction. Because of the annual operating savings, the officials said the U.S. would make up the initial construction costs in three to five years.

And as with anything that Obama proposes, the leaders of the GOP are already barking back against it. Here’s America’s largest freshwater turtle, Senate Majority Leader Mitch McConnell, saying that he and his congressional cronies are against Barack’s plan, but that they’ll review it (which begs the question: how do you know you’re against something before you even read it? Mitch is hung up on transporting terrorists, but perhaps a solution lies within?):
