Here’s the pertinent part of the veto statement:
I am returning herewith without my approval H.R. 1735, the “National Defense Authorization Act for Fiscal Year 2016.” While there are provisions in this bill that I support, including the codification of key interrogation-related reforms from Executive Order 13491 and positive changes to the military retirement system, the bill would, among other things, constrain the ability of the Department of Defense to conduct multi-year defense planning and align military capabilities and force structure with our national defense strategy, impede the closure of the detention facility at Guantanamo Bay, and prevent the implementation of essential defense reforms. . . .
I have repeatedly called upon the Congress to work with my Administration to close the detention facility at Guantanamo Bay, Cuba, and explained why it is imperative that we do so. As I have noted, the continued operation of this facility weakens our national security by draining resources, damaging our relationships with key allies and partners, and emboldening violent extremists. Yet in addition to failing to remove unwarranted restrictions on the transfer of detainees, this bill seeks to impose more onerous ones. The executive branch must have the flexibility, with regard to those detainees who remain at Guantanamo, to determine when and where to prosecute them, based on the facts and circumstances of each case and our national security interests, and when and where to transfer them consistent with our national security and our humane treatment policy. Rather than taking steps to bring this chapter of our history to a close, as I have repeatedly called upon the Congress to do, this bill aims to extend it. . . .
Because of the manner in which this bill would undermine our national security, I must veto it.
