The federal government of the United States is the central government entity established by the United States Constitution, which shares sovereignty over the United States of America with the governments of the individual U.S. states. It is formally known as the Government of the United States of America.
The U.S. federal regime dates from 1790 and is considered to be the first modern national federation government in the world. Even so, the details of American federalism have been debated since the establishment and ordination of the constitution, with some parties arguing for expansive national powers while others have strictly interpreted the constitutional enumerations of the national government's powers.
Since the U.S. Civil War, the powers of the federal government have tended to expand, although there have been periods when state's rights proponents have succeeded in limiting federal power through legislative action, executive prerogative or by constitutional interpretation of the courts.[1][2]
The seat of the federal government is in the District of Columbia.
Congress is the legislative branch of the federal government. It is bicameral, comprising the House of Representatives and the Senate. The House of Representatives consists of 435 voting members, each of whom represents a congressional district and serves for a two-year term. In addition to the 435 voting members, there are five non-voting members, consisting of four delegates and one resident commissioner. There is one delegate each from the District of Columbia, Guam, Virgin Islands, and American Samoa, and the resident commissioner is from Puerto Rico.[3] House seats are apportioned among the states by population; in contrast, each state has two senators, regardless of population. There are a total of 100 senators (as there are currently 50 states), who serve six-year terms (one third of the Senate stands for election every two years). Each congressional chamber (House or Senate) has particular exclusive powers—the Senate must give "advice and consent" to many important Presidential appointments, and the House must introduce any bills for the purpose of raising revenue. The consent of both chambers is required to pass any legislation, which then may only become law by being signed by the President; if the President vetoes such legislation, however, both houses of Congress must then re-pass the legislation, but by a two-thirds majority of each chamber, in order to make such legislation law without the need for the President's signature. The powers of Congress are limited to those enumerated in the Constitution; all other powers are reserved to the states and the people. The Constitution also includes the "Necessary and Proper Clause", which grants Congress the power to "make all laws which shall be necessary and proper for carrying into execution the foregoing powers." Members of the House and Senate are elected by first-past-the-post voting in every state except Louisiana and Washington, which have runoffs.
Article I, Section 2, paragraph 2 of the U.S. Constitution gives each chamber the power to "determine the rules of its proceedings." From this provision were created congressional committees, which do the work of drafting legislation and conducting congressional investigations into national matters. The 108th Congress (2003-2005) had 19 standing committees in the House and 17 in the Senate, plus four joint permanent committees with members from both houses overseeing the Library of Congress, printing, taxation, and the economy. In addition, each house may name special, or select, committees to study specific problems. Today, much of the congressional workload is borne by subcommittees, of which there are some 150.
The Constitution grants numerous powers to Congress. Enumerated in Article I, Section 8, these include the powers to levy and collect taxes; to coin money and regulate its value; provide for punishment for counterfeiting; establish post offices and roads, promote progress of science by issuing patents, create federal courts inferior to the Supreme Court, define and punish piracies and felonies, declare war, raise and support armies, provide and maintain a navy, make rules for the regulation of land and naval forces, provide for, arm, and discipline the militia, exercise exclusive legislation in the District of Columbia, and to make laws necessary to properly execute these powers.
Congressional oversight is intended to prevent waste and fraud, protect civil liberties and individual rights, ensure executive compliance with the law, gather information for making laws and educating the public, and evaluate executive performance.[4]
It applies to cabinet departments, executive agencies, regulatory commissions, and the presidency. Congress's oversight function takes many forms:
The executive power in the federal government is vested in the President of the United States,[5] although power is often delegated to the Cabinet members and other officials.[6][7] The President and Vice President are elected as running mates for a maximum of two[8] four-year terms[5] by the Electoral College, for which each state, as well as the District of Columbia, is allocated a number of seats based on its representation (or ostensible representation, in the case of D.C.) in both houses of Congress.[5][9]
The executive branch consists of the President and delegates. The President is both the head of state and government, as well as the military commander-in-chief and chief diplomat. The President, according to the Constitution, must "take care that the laws be faithfully executed," and "preserve, protect, and defend the Constitution." The President presides over the executive branch of the federal government, a vast organization numbering about 4 million people, including 1 million active-duty military personnel. The forty-fourth and current president is Barack Obama.
The President may sign legislation passed by Congress into law or may veto it, preventing it from becoming law unless two-thirds of both houses of Congress vote to override the veto. The President may, with the consent of two-thirds of the Senate, make treaties with foreign nations. The President may be impeached by a majority in the House and removed from office by a two-thirds majority in the Senate for "treason, bribery, or other high crimes and misdemeanors." The President may not dissolve Congress or call special elections but does have the power to pardon, or release, criminals convicted of offenses against the federal government (except in cases of impeachment), enact executive orders, and (with the consent of the Senate) appoint Supreme Court justices and federal judges.
The Vice President is the second-highest executive official of the government. As first in the U.S. presidential line of succession, the Vice President becomes President upon the death, resignation, or removal of the President, which has happened nine times in U.S. history. Under the Constitution, the Vice President is President of the Senate. By virtue of the Vice President's role as President of the Senate, he or she is the nominal head of the United States Senate. In that capacity, the Vice President is allowed to vote in the Senate, but only when necessary to break a tied vote. Pursuant to the Twelfth Amendment, the Vice President presides over the joint session of Congress when it convenes to count the vote of the Electoral College. While the Vice President's only constitutionally prescribed functions, aside from presidential succession, relate to his role as President of the Senate, the office is now commonly viewed as a member of the executive branch of the federal government. The U.S. Constitution does not expressly assign the office to any one branch, causing scholars to dispute whether it belongs to the executive branch, the legislative branch, or both.[10][11]
