On Dec 12th:
Statement by President Donald J. Trump on H.R. 2810
it states: "Today, I have signed into law H.R. 2810, the “National Defense Authorization Act for Fiscal Year 2018.” This Act authorizes fiscal year 2018 appropriations for critical Department of Defense (DOD) national security programs, provides vital benefits for military personnel and their families, and includes authorities to facilitate ongoing military operations around the globe. I am very appreciative that the Congress has passed this bill to provide the DOD with the resources it needs to support our Armed Forces and keep America safe. I note, however, that the bill includes several provisions that raise constitutional concerns.
…
Several provisions of the bill, including sections 1069, 1231, 1232, 1239, 1239A, 1258, 1259, 1263, 1271, 1279A, and 1607, could potentially dictate the position of the United States in external military and foreign affairs and, in certain instances, direct the conduct of international diplomacy. My Administration will treat these provisions consistent with the President’s exclusive constitutional authorities as Commander in Chief and as the sole representative of the Nation in foreign affairs to determine the terms on which recognition is given to foreign sovereigns and conduct the Nation’s diplomacy."
