The war on terror, officially the Global War on Terrorism (GWOT), is an ongoing international counter-terrorism military campaign initiated by the United States following the September 11 attacks. The targets of the campaign are primarily Islamic terrorist groups, with prominent targets including al-Qaeda and the Islamic State of Iraq and the Levant (ISIL).The "war on terror" uses war as a metaphor to describe a variety of actions which fall outside the traditional definition of war taken to eliminate international terrorism. 43rd President of the United States George W. Bush first used the term "war on terrorism" on 16 September 2001, and then "war on terror" a few days later in a formal speech to Congress. Bush indicated the enemy of the war on terror as "a radical network of terrorists and every government that supports them." The initial conflict was aimed at al-Qaeda, with the main theater in Afghanistan and Pakistan, a region that would later be referred to as "AfPak".The term "war on terror" was immediately criticized by individuals including Richard Myers, then Chairman of the Joint Chiefs of Staff, and eventually more nuanced terms came to be used by the Bush administration to define the campaign. While "war on terror" was never used as a formal designation of U.S. operations, a Global War on Terrorism Service Medal was issued by the U.S. Armed Forces.

The Obama administration sought to avoid use of the term and instead preferred to use the term Overseas Contingency Operation. On 23 May 2013, Obama announced that the Global War on Terror was over, indicating that the U.S. would not wage war against a tactic but would instead focus on a specific group of terrorist networks. The rise of ISIL led to the global Operation Inherent Resolve, and an international campaign to destroy the terrorist organization.

The notion of a "War on Terror" was contentious, with critics charging that it has been used to reduce civil liberties and infringe upon human rights, such as controversial actions by the U.S. including surveillance, torture, and extraordinary rendition, and drone strikes that resulted in the deaths of suspected terrorists but also civilians. Many of the U.S.' actions were supported by other countries, including the 54 countries that were involved with

CIA black sites, or those that assisted with drone strikes.Criticism of the war on terror has focused on its morality, efficiency, and cost. According to a 2021 study conducted by the Watson Institute for International and Public Affairs, the several post-9/11 wars participated in by the United States in its war against terror have caused the displacement, conservatively calculated, of 38 million people in Afghanistan, Pakistan, Iraq, Libya, Syria, Yemen, Somalia, and the Philippines; 26.7 million people have returned home following displacement. The study estimated these wars caused the deaths of 897,000 to 929,000 people, including over 364,000 civilians, and cost $8 trillion. Critics accuse participating governments of using the "War on Terror" to repress minorities or sideline domestic opponents, of mainstreaming Islamophobia, and have criticized negative impacts to health and the environment, resulting from the "War on Terror". Critics assert that the term "war" is not appropriate in this context (much like the term "war on drugs") since terror is not an identifiable enemy and it is unlikely that international terrorism can be brought to an end by military means.

The United States Congress is the legislature of the federal government of the United States. It is bicameral, being composed of a lower body, the House of Representatives, and an upper body, the Senate. The Congress meets in the United States Capitol in Washington, D.C. Both senators and representatives are chosen through direct election, though vacancies in the Senate may be filled by a governor's appointment. Congress has 535 voting members: 100 senators and 435 representatives. The vice president of the United States has a vote in the Senate only when senators are evenly divided. The House of Representatives has six non-voting members.The sitting of a Congress is for a two-year term, at present, beginning every other January. Elections are held every even-numbered year on Election Day. The members of the House of Representatives are elected for the two-year term of a Congress. The Reapportionment Act of 1929 establishes that they be elected in single-member constituencies or districts by first-past-the-post and that Congressional districts be apportioned to states by population every ten years using the United States Census results, provided that each state has at least one Congressional representative. Each senator is elected at-large in their state for a six-year term, with terms staggered, so every two years approximately one-third of the Senate is up for election. Each state, regardless of population or size, has two senators, so currently, there are 100 senators for the 50 states.

Article One of the United States Constitution requires that members of Congress must be at least 25 years old (House) or at least 30 years old (Senate), have been a citizen of the United States for seven (House) or nine (Senate) years, and be an inhabitant of the state which they represent. Members in both chambers may stand for re-election an unlimited number of times.

The Congress was created by the Constitution of the United States and first met in 1789, replacing in its legislative function the Congress of the Confederation. Although not legally mandated, in practice since the 19th century, Congress members are typically affiliated with one of the two major parties, the Democratic Party or the Republican Party, and only rarely with a third party or independents affiliated with no party. In the case of the latter, the lack of affiliation with a political party does not mean that such members are unable to caucus with members of the political parties. Members can also switch parties at any time, although this is quite uncommon.
