Cmdr. Gary Ross, a Pentagon spokesman, confirmed the visit to Colorado, while stressing that no sites had been selected.
"The assessment team will meet with facility staff to discuss the existing facilities, engineering considerations, force protection, troop housing, security, transportation, information security, contracting and other operational issues," he said. "The facilities also will be assessed for their ability to serve as military commission sites."
Senator Cory Gardner, a Republican, declared last month that Florence should not be on the table as a Guantánamo replacement because bringing detainees there would endanger "the safety and security of Coloradans," and he reiterated that position on Friday.
"I remain opposed to any plan to bring Guantánamo terrorists to Colorado," he said in a statement. "I call on the Obama administration to immediately halt any consideration of this irresponsible idea."
Adam Bozzi, a spokesman for the state's other senator, Michael Bennet, a Democrat, also expressed wariness.
"The Department of Defense has no authority to transfer these prisoners or make such modifications, and they have made no case to do so," he said.
From the New York Times:
The administration says the Guantánamo prison should be closed because it is a symbol that fuels anti-American sentiment and because it is far more expensive to house a detainee there than in a domestic prison.
Mr. Obama's plan to close the prison involves transferring the 53 detainees who have been recommended for release if security conditions can be met in the receiving country, and bringing the remaining 61 detainees to a prison on domestic soil. He has urged Congress to rescind the statute that bars transferring any detainees into the United States, but a pending military authorization bill would instead extend it.
The bill would also mandate that the administration provide a "plan" to Congress for closing the prison. It had promised this year to give one to Senator John McCain, the Arizona Republican who is chairman of the Senate Armed Services Committee, but has not yet done so.
