Guest columnist Nancy Talanian: Mr. President, it’s time to close Guantánamo Bay Prison FILE - In this Nov. 21, 2013, file photo reviewed by the U.S. military, dawn arrives at the now closed Camp X-Ray, which was used as the first detention facility for al-Qaida and Taliban militants who were captured after the Sept. 11 attacks at Guantanamo Bay Naval Base, Cuba. U.S. officials say the Pentagon’s long-awaited plan to shut down the detention center at Guantanamo Bay, Cuba, and transfer the remaining detainees to a facility in the U.S. calls for up to 475 million in construction costs, but would save as much as 180 million per year in operating costs.
