U.S. federal government in the context of "Indian reservation"

The National Reconnaissance Office (NRO) is a member of the United States Intelligence Community and an agency of the United States Department of Defense which designs, builds, launches, and operates the reconnaissance satellites of the U.S. federal government. It provides satellite intelligence to several government agencies, particularly signals intelligence (SIGINT) to the National Security Agency (NSA), imagery intelligence (IMINT) to the National Geospatial-Intelligence Agency (NGA), and measurement and signature intelligence (MASINT) to the Defense Intelligence Agency (DIA). The NRO announced in 2023 that it plans within the following decade to quadruple the number of satellites it operates and increase the number of signals and images it delivers by a factor of ten.

NRO is considered, along with the Central Intelligence Agency (CIA), NSA, DIA, and NGA, to be one of the "big five" U.S. intelligence agencies. The NRO is headquartered in Chantilly, Virginia, 2 miles (3.2 km) south of Washington Dulles International Airport.

Admission to the Union is provided by the Admissions Clause of the United States Constitution in Article IV, Section 3, Clause 1, which authorizes the United States Congress to admit new states into the Union beyond the thirteen states that already existed when the Constitution came into effect. The Constitution went into effect on June 21, 1788, in the nine states that had ratified it, and the U.S. federal government began operations under it on March 4, 1789, when it was in effect in 11 out of the 13 states. Since then, 37 states have been admitted into the Union. Each new state has been admitted on an equal footing with those already in existence.

Of the 37 states admitted to the Union by Congress, all but six have been established within existing U.S. organized incorporated territories. A state that was so created might encompass all or part of a territory. When the people of a territory or a region have grown to a sufficient population and have made their desire for statehood known to the federal government, Congress in most cases has passed an enabling act, authorizing the people of that territory or region to frame a proposed state constitution as a step toward admission to the Union. The use of an enabling act has been a common historic practice, but several states were admitted to the Union without one.

The vice president of the United States (VPOTUS, or informally, veep) is the second-highest ranking office in the executive branch of the U.S. federal government, after the president of the United States, and ranks first in the presidential line of succession. The vice president is also an officer in the legislative branch, as the president of the Senate. In this capacity, the vice president is empowered to preside over the United States Senate, but may not vote except to cast a tie-breaking vote. The vice president is elected at the same time as the president to a four-year term of office by the people of the United States through the Electoral College, but the electoral votes are cast separately for these two offices. Following the passage in 1967 of the Twenty-fifth Amendment to the US Constitution, a vacancy in the office of vice president may be filled by presidential nomination and confirmation by a majority vote in both houses of Congress. This was based on the Tyler Precedent set in 1841 when John Tyler became the first vice president to take over for a deceased president following the death of William Henry Harrison.

The modern vice presidency is a position of significant power and is widely seen as an integral part of a president's administration. The presidential candidate selects the candidate for the vice presidency as their running mate in the lead-up to the presidential election. While the exact nature of the role varies in each administration, since the vice president's service in office is by election, the president cannot dismiss the vice president, and the personal working-relationship with the president varies, most modern vice presidents serve as a key presidential advisor, governing partner, and representative of the president. The vice president is also a statutory member of the United States Cabinet and United States National Security Council and thus plays a significant role in executive government and national security matters. As the vice president's role within the executive branch has expanded, the legislative branch role has contracted; for example, vice presidents now preside over the Senate only infrequently.

The United States Department of State (DOS), or simply the State Department, is an executive department of the U.S. federal government responsible for the country's foreign policy and relations. Equivalent to the ministry of foreign affairs of other countries, its primary duties are advising the U.S. president on international relations, administering diplomatic missions, negotiating international treaties and agreements, protecting citizens abroad and representing the U.S. at the United Nations. The department is headquartered in the Harry S Truman Building, a few blocks from the White House, in the Foggy Bottom neighborhood of Washington, D.C.; "Foggy Bottom" is thus sometimes used as a metonym.

Established in 1789 as the first administrative arm of the U.S. executive branch, the State Department is considered among the most powerful and prestigious executive agencies. It is headed by the U.S. secretary of state, who reports directly to the U.S. president and is a member of the Cabinet. Analogous to a foreign minister, the secretary of state serves as the federal government's chief diplomat and representative abroad, and is the first Cabinet official in the order of precedence and in the presidential line of succession. The position is currently held by Marco Rubio, who was appointed by President Donald Trump and confirmed by the U.S. Senate on January 20, 2025, by a vote of 99–0.

The alphabet agencies, or New Deal agencies, were the U.S. federal government agencies created as part of the New Deal of President Franklin D. Roosevelt. The earliest agencies were created to combat the Great Depression in the United States and were established during Roosevelt's first 100 days in office in 1933. In total, at least 69 offices were created during Roosevelt's terms of office as part of the New Deal. Some alphabet agencies were established by Congress, such as the Tennessee Valley Authority. Others were established through Roosevelt executive orders, such as the Works Progress Administration and the Office of Censorship, or were part of larger programs such as the many that belonged to the Works Progress Administration. Some of the agencies still exist today, while others have merged with other departments and agencies or were abolished.

The agencies were sometimes referred to as alphabet soup. Libertarian author William Safire notes that the phrase "gave color to the charge of excessive bureaucracy." Democrat Al Smith, who turned against Roosevelt, said his government was "submerged in a bowl of alphabet soup." "Even the Comptroller-General of the United States, who audits the government's accounts, declared he had never heard of some of them." While previously all monetary appropriations had been separately passed by Act of Congress, as part of their power of the purse; the National Industrial Recovery Act allowed Roosevelt to allocate $3.3 billion without Congress (as much as had been previously spent by government in ten years time), through executive orders and other means. These powers were used to create many of the alphabet agencies. Other laws were passed allowing the new bureaus to pass their own directives within a wide sphere of authority. Even though the National Industrial Recovery Act was found to be unconstitutional, many of the agencies created under it remained.
