Last week Obama cited Guantanamo's astronomical expense as one reason to close the prison. Just one inmate costs $900,000 per year - the same 12 weeks of White House tours for the public, which can be had for only $74,000 a week, according to Reuters.
With 166 inmates still in Gitmo, the prison costs taxpayers $150 million per year. That's around 15 times the cost of imprisonment in maximum-security prisons within the US, which come in at $60,000 per prisoner.
Why the huge cost? It's because everything - food, clothing, military and construction equipment - has to be shipped to Cuba. All personnel and lawyers have to be flown to and from the island.
Closing the prison could free up money for other items cut under sequestration, like Meals on Wheels for the elderly.
But no one, including Obama, has come up with a politically-feasible plan for dealing with the remaining prisoners. Nine have been charged or convicted, 24 could still be prosecuted, and 47 others are considered too dangerous for release, Reuters reports. The rest have been cleared for release but have nowhere to go.
