The National Defense Authorization Act (NDAA) for Fiscal Year 2012 () is a United States federal law which among other things specifies the budget and expenditures of the United States Department of Defense. The bill passed the U.S. House on December 14, 2011, the U.S. Senate on December 15, 2011, and was signed into United States law on December 31, 2011, by President Barack Obama. The Act authorizes $662 billion in funding, among other things "for the defense of the United States and its interests abroad". In a signing statement, President Obama described the Act as addressing national security programs, Department of Defense health care costs, counter-terrorism within the United States and abroad, and military modernization. The Act also imposes new economic sanctions against Iran (section 1245), commissions appraisals of the military capabilities of countries such as Iran, China, and Russia, and refocuses the strategic goals of NATO towards "energy security". The Act also increases pay and healthcare costs for military service members and gives governors the ability to request the help of military reservists in the event of a hurricane, earthquake, flood, terrorist attack, or other disaster. The most controversial provisions to receive wide attention were contained in subsections 1021–1022 of Title X, Subtitle D, entitled "Counter-Terrorism", authorizing the indefinite military detention of persons the government suspects of involvement in terrorism, including U.S. citizens arrested on American soil. Although the White House and Senate sponsors maintain that the Authorization for Use of Military Force (AUMF) already grants presidential authority for indefinite detention, the Act states that Congress "affirms" this authority and makes specific provisions as to the exercise of that authority. The detention provisions of the Act have received critical attention by, among others, the American Civil Liberties Union (ACLU), the Bill of Rights Defense Committee, and some media sources which are concerned about the scope of the President's authority, including contentions that those whom they claim may be held indefinitely could include U.S. citizens arrested on American soil, including arrests by members of the Armed Forces. The detention powers currently face legal challenge. Section 818 This section contains "critical provisions" reflecting a bipartisan amendment regarding counterfeit electronic parts in the Defense Department's supply chain, adopted following concerns raised by Senators Carl Levin and John McCain, chairman and ranking member respectively of the Senate Committee on Armed Services, regarding counterfeit electronic parts highlighted in an investigation commenced in March
