"Today I have signed into law H.R. 4310, the "National Defense Authorization Act for Fiscal Year 2013." I have approved this annual defense authorization legislation, as I have in previous years, because it authorizes essential support for service members and their families, renews vital national security programs, and helps ensure that the United States will continue to have the strongest military in the world.
"Even though I support the vast majority of the provisions contained in this Act, which is comprised of hundreds of sections spanning more than 680 pages of text, I do not agree with them all. Our Constitution does not afford the President the opportunity to approve or reject statutory sections one by one. I am empowered either to sign the bill, or reject it, as a whole. In this case, though I continue to oppose certain sections of the Act, the need to renew critical defense authorities and funding was too great to ignore...
"...Section 533 is an unnecessary and ill-advised provision, as the military already appropriately protects the freedom of conscience of chaplains and service members. The Secretary of Defense will ensure that the implementing regulations do not permit or condone discriminatory actions that compromise good order and discipline or otherwise violate military codes of conduct. My Administration remains fully committed to continuing the successful implementation of the repeal of Don't Ask, Don't Tell, and to protecting the rights of gay and lesbian service members; Section 533 will not alter that.
"Several provisions in the bill also raise constitutional concerns...Sections 1022, 1027 and 1028 continue unwise funding restrictions that curtail options available to the executive branch. Section 1027 renews the bar against using appropriated funds for fiscal year 2012 to transfer Guantanamo detainees into the United States for any purpose. I continue to oppose this provision, which substitutes the Congress's blanket political determination for careful and fact-based determinations, made by counterterrorism and law enforcement professionals, of when and where to prosecute Guantanamo detainees. For decades, Republican and Democratic administrations have successfully prosecuted hundreds of terrorists in Federal court. Those prosecutions are a legitimate, effective, and powerful tool in our efforts to protect the Nation, and in certain cases may be the only legally available process for trying detainees. Removing that tool from the executive branch undermines our national security. Moreover, this provision would, under certain circumstances, violate constitutional separation of powers principles.
"Section 1028 fundamentally maintains the unwarranted restrictions on the executive branch's authority to transfer detainees to a foreign country. This provision hinders the Executive's ability to carry out its military, national security, and foreign relations activities and would, under certain circumstances, violate constitutional separation of powers principles. The executive branch must have the flexibility to act swiftly in conducting negotiations with foreign countries regarding the circumstances of detainee transfers. The Congress designed these sections, and has here renewed them once more, in order to foreclose my ability to shut down the Guantanamo Bay detention facility. I continue to believe that operating the facility weakens our national security by wasting resources, damaging our relationships with key allies, and strengthening our enemies. My Administration will interpret these provisions as consistent with existing and future determinations by the agencies of the Executive responsible for detainee transfers. And, in the event that these statutory restrictions operate in a manner that violates constitutional separation of powers principles, my Administration will implement them in a manner that avoids the constitutional conflict."
