Joseph McCarthy in the context of "John Searle"

Robert Francis Kennedy (November 20, 1925 – June 6, 1968), also known by his initials RFK, was an American politician and lawyer who served as a U.S. senator from New York from 1965 until his assassination in 1968. A member of the Democratic Party, Kennedy previously served as the 64th United States attorney general from 1961 to 1964. Like his brothers John F. Kennedy and Ted Kennedy, he was a prominent member of the Democratic Party and is considered an icon of modern American liberalism.

Born into the prominent Kennedy family in Brookline, Massachusetts, Kennedy attended Harvard University, and later received his law degree from the University of Virginia. He began his career as a correspondent for The Boston Post and as a lawyer at the Justice Department, but later resigned to manage his brother John's successful campaign for the U.S. Senate in 1952. The following year, Kennedy worked as an assistant counsel to the Senate committee chaired by Senator Joseph McCarthy. He gained national attention as the chief counsel of the Senate Labor Rackets Committee from 1957 to 1959, where he publicly challenged Teamsters president Jimmy Hoffa over the union's corrupt practices. Kennedy resigned from the committee to conduct his brother's successful campaign in the 1960 presidential election. He was appointed United States attorney general at the age of 35, one of the youngest cabinet members in American history. Kennedy served as John's closest advisor until the latter's assassination in 1963.

The House Committee on Un-American Activities (HCUA), popularly the House Un-American Activities Committee (HUAC), was an investigative committee of the United States House of Representatives created in 1938. Their goal was to investigate alleged disloyalty and subversive activities on the part of private citizens, public employees, and those organizations suspected of having communist ties. It became a standing (permanent) committee in 1946. Then, from 1969 and onward, it was known as the House Committee on Internal Security. When the House abolished the committee in 1975, its functions were transferred to the House Judiciary Committee.

The committee's anti-communist investigations are often associated with McCarthyism, although Joseph McCarthy himself (as a U.S. senator) had no direct involvement with the House committee. McCarthy was the chairman of the Government Operations Committee and its Permanent Subcommittee on Investigations of the U.S. Senate, not the House.

McCarthyism is a political practice defined by the political repression and persecution of left-wing individuals and a campaign spreading fear of communist and Soviet influence on American institutions and of Soviet espionage in the United States during the late 1940s through the 1950s, heavily associated with the Second Red Scare, also known as the McCarthy era. After the mid-1950s, U.S. senator Joseph McCarthy, who had spearheaded the campaign, gradually lost his public popularity and credibility after several of his accusations were found to be false. The U.S. Supreme Court under Chief Justice Earl Warren made a series of rulings on civil and political rights that overturned several key laws and legislative directives, and helped bring an end to the Second Red Scare.

Historians have suggested since the 1980s that as McCarthy's involvement was less central than that of others, a different and more accurate term should be used instead that more accurately conveys the breadth of the phenomenon, and that the term McCarthyism is, in the modern day, outdated. Ellen Schrecker has suggested that Hooverism, after FBI head J. Edgar Hoover, is more appropriate. Following the end of the Cold War, unearthed documents revealed substantial Soviet spy activity in the United States, although many of the agents were never properly identified by McCarthy.
