Social Studies is a studio album by Loudon Wainwright III, released in 1999.
 The album comprises various topical and satirical songs, originally produced for National Public Radio and based upon then-current issues and events, such as the Tonya Harding scandal, the O. J. Simpson murder trial, the lead-up to Y2K, and controversies surrounding comments made by former Republican U.S. Senator Jesse Helms.
The Fulbright Hearings refers to any of the set of U.S. Senate Foreign Relations Committee hearings on Vietnam conducted between 1966 and 1971.
 This article concerns those held by the U.S. Senate in 1971 relating to the Vietnam War.
 By April 1971, with at least seven pending legislative proposals concerning the war, the Senate Foreign Relations Committee, chaired by Democratic Senator J. William Fulbright of Arkansas began to hear testimony.
 The 22 hearings, titled "Legislative Proposals Relating to the War in Southeast Asia", were held on eleven different days between April 20, 1971, and May 27, 1971.
 The hearings included testimony and debate from several members of Congress, as well as from representatives of interested pro-war and anti-war organizations.
The Kerry Committee report, formally titled "Drugs, Law Enforcement and Foreign Policy", was the final report of an investigation by the Senate Foreign Relations Committee's Subcommittee on Terrorism, Narcotics, and International Operations.
 The report examined the problems that drug cartels and drug money laundering in South and Central America and the Caribbean posed for American law enforcement and foreign policy.
 The Sub-Committee was chaired at the time by Senator John Kerry, so that the report is often referred to under his name.
Jesse Alexander Helms Jr. (October 18, 1921 – July 4, 2008) was an American politician and a leader in the conservative movement.
 He was elected five times as a Republican to the United States Senate from North Carolina.
 As chairman of the Senate Foreign Relations Committee from 1995 to 2001 he had a major voice in foreign policy.
 Helms helped organize and fund the conservative resurgence in the 1970s, focusing on Ronald Reagan's quest for the White House as well as helping many local and regional candidates.
Donna M. Hughes (born 1954) is professor and Eleanor M. and Oscar M. Carlson Endowed Chair of the Women's Studies Program at the University of Rhode Island, a leading international researcher on human trafficking, and also sits on the editorial board of "Sexualization, Media, and Society".
 She is frequently consulted by governments and non-governmental organizations on policy related to women's human rights, particularly on trafficking of women and girls for sexual exploitation.
 She has testified before the U.S. House International Relations Committee, the Senate Foreign Relations Committee, the Moscow Duma, and the Czech Parliament.
Theodore Francis Green (October 2, 1867May 19, 1966) was an American politician from Rhode Island.
 A Democrat, Green served as the 57th Governor of Rhode Island (1933–1937) and in the United States Senate (1937–1961).
 He was a wealthy aristocratic Yankee from an old family who was a strong supporter of Wilsonian internationalism during the Democratic administrations of Franklin Roosevelt and Harry Truman (1933–53).
 Thanks to seniority he served briefly as chairman of the Senate Foreign Relations Committee.
 At the time of his retirement in 1961, he set the record at age 92 of the oldest person to serve in the Senate; which was subsequently broken by Strom Thurmond.
The Case–Church Amendment was legislation approved by the U.S. Congress in June 1973 that prohibited further U.S. military activity in Vietnam, Laos and Cambodia unless the president secured Congressional approval in advance.
 This ended direct U.S. military involvement in the Vietnam War, although the U.S. continued to provide military equipment and economic support to the South Vietnamese government.
 It is named for its principal co-sponsors, Senators Clifford P. Case (R-NJ) and Frank Church (D-ID).
 The Amendment was defeated 48–42 in the U.S. Senate in August 1972, but revived after the 1972 election.
 It was reintroduced on January 26, 1973 and approved by the Senate Foreign Relations Committee on May 13.
 When it became apparent that the Amendment would pass, President Richard Nixon and Secretary of State Henry Kissinger, lobbied frantically to have the deadline extended.
 It passed the United States Congress with bipartisan support in June by a margin of 325–86 in the House, and 73–16 in the Senate.
 Both of these margins were greater than the two-thirds majority required to override a presidential veto.
 Although U.S. ground forces had been withdrawn earlier under a policy called Vietnamization, bombing continued until August 15, 1973, the deadline set by the Amendment.
Ernest Warren Lefever (November 12, 1919 – July 29, 2009) was an American political theorist and foreign affairs expert who founded the Ethics and Public Policy Center in 1976 and was nominated for a State Department post by President Ronald Reagan, but withdrew after his nomination was rejected by the Senate Foreign Relations Committee.

 He is currently Emeritus Professor of Science and Security at King's College London.

James William Fulbright (April 9, 1905 – February 9, 1995) was a United States Senator representing Arkansas from January 1945 until his resignation in December 1974.
 Fulbright is the longest serving chairman in the history of the Senate Foreign Relations Committee.
 A Southern Democrat and a staunch multilateralist who supported the creation of the United Nations, he was also a segregationist who signed the Southern Manifesto.
 Fulbright opposed McCarthyism and the House Un-American Activities Committee and later became known for his opposition to American involvement in the Vietnam War.
 His efforts to establish an international exchange program eventually resulted in the creation of a fellowship program which bears his name, the Fulbright Program.
