Senator Dianne Feinstein recently commissioned a Government Accountability Office report identifying prison facilities in the continental United States suitable for detainees currently held in Guantánamo Bay. After Fox News reported about this document, her office released a statement saying that the GAO's study "demonstrates that if the political will exists, we could finally close Guantánamo without imperiling our national security."
Independently, a coalition of advocacy groups sent President Obama an open letter on Tuesday urging him to veto the 2013 National Defense Authorization Act if it impedes the administration's ability to close Guantánamo.
