In July 1964, President Lyndon Johnson summoned Attorney General Robert Kennedy to the Oval Office. Kennedy had served as attorney general for three and a half years and ran the Department of Justice, which formally included the FBI. Through his years at Justice, he had deep experience with intelligence gathering and surveillance, and he had himself authorized wiretaps. He understood exactly how the machinery worked.
He walked into the Oval Office and sat down across from the man he despised more than any other figure in American politics. As he sat there, he noticed something: the buttons on the control panel of Johnson's telephone were depressed. The recording device was running.
Kennedy said what he needed to say. According to Theodore White's documented account, he was guarded throughout the entire conversation. He knew he was being recorded. He gave Johnson nothing.
This is the story of what Robert Kennedy did when he realized Lyndon Johnson was recording him, and what that discovery revealed about the most consequential political feud in modern American history.
To understand what it meant for RFK to know about Johnson's recording system, you have to understand where the relationship between the two men stood by the summer of 1964. It was not a relationship at all. It was a cold war conducted inside the same building between two men who had despised each other for years before either held significant power in the Kennedy administration.
The hostility was mutual, documented, and deep. Robert Kennedy had loathed Lyndon Johnson since the 1950s. Johnson embodied everything RFK distrusted in a politician: a man who used power as a personal tool, shifted positions based on calculation rather than conviction, and treated people as instruments. RFK had grown up watching his father work the hard politics of the Democratic Party machine, and he developed a sharp contempt for its practitioners. Johnson was its most prominent practitioner.
Johnson's feelings toward Kennedy were equally documented and equally blunt. He resented the ease with which the Kennedy family won public affection, and the way Kennedys moved through rooms and made people loyal to them without visible effort. He resented that RFK, whom he considered a ruthless politician with no real achievements of his own, was treated as a moral figure. He resented being treated as a subordinate by Kennedy's staff. He resented Robert Kennedy more than anyone else.
The assassination of President Kennedy on November 22, 1963, did not end the conflict. It sharpened it. According to multiple documented accounts, including those of Arthur Schlesinger Jr., Kennedy's authorized biographer, Robert Kennedy believed Johnson moved with indecent speed to consolidate his own authority. Kennedy did not publicly accuse Johnson of any impropriety, but the documented record of his private feelings in those first weeks is unmistakable. He was shattered by grief and angry at what he considered a lack of grace in Johnson's actions in the hours immediately after his brother's death.
For his part, Johnson inherited a staff fiercely loyal to John Kennedy and, in most cases, therefore loyal to Robert Kennedy. He moved carefully but firmly to establish his own authority. Kennedy's people initially stayed in their posts. Johnson needed them, needed the continuity they represented, and needed to send a public signal that he respected his predecessor's legacy. But everyone in the White House understood that the center of gravity had shifted permanently.
Johnson had been recording his conversations since his Senate days. He began taping as vice president, and from the moment he became president on November 22, 1963, the White House recording system was ready to run. The first recording Johnson made as president was aboard Air Force One on the flight back from Dallas. The system captured telephone calls and, through hidden microphones, some personal conversations in the Oval Office.
Johnson's recording operation, according to the documented assessment of the Miller Center at the University of Virginia, which has studied and published thousands of hours of Johnson's tapes, was comprehensive and systematic. Robert Kennedy learned of Johnson's recording system, according to the Miller Center's documented introduction to the presidential recordings, early in Johnson's presidency, possibly through Schlesinger or through Evelyn Lincoln, John Kennedy's personal secretary, who remained at the White House.
Information about Johnson's recordings was later disclosed to journalist and historian Theodore White, who was writing his account of the 1964 presidential campaign for his "Making of the President" series. The specific meeting at which Robert Kennedy's awareness of the recording system became clearly documented is the July 1964 meeting at which Johnson told Kennedy he would not be selected as the vice presidential nominee in the coming election.
That meeting is one of the most closely described private conversations in modern American political history. Multiple accounts of it exist. What Theodore White documented in "The Making of the President 1964," published in 1965, is the clearest contemporary account of Robert Kennedy's behavior in light of his awareness. White wrote that Kennedy was guarded throughout the entire conversation. He knew the president was in the habit of recording conversations in his office, he could see the buttons depressed, and the recorder was running.
The attorney general said, "Well." He offered his help and support. That is the documented record of what Robert Kennedy did when he realized he was being recorded by Johnson. He did not confront Johnson about the recording system at that meeting. Instead, the documented evidence shows he remained reserved, spoke little, and stayed focused on the subject at hand. It cannot be stated with certainty that he chose his words carefully because of the recording, but his restraint is consistent with his knowledge of Johnson's recording practices.
The July 1964 meeting to exclude the vice president is one of the most documented and analyzed moments in the Johnson-Kennedy relationship. Johnson's motive was clear. He did not want Robert Kennedy as his vice president. Kennedy's presence would create the impression of a co-presidency and a constant reminder that Johnson was an accident of history, not the legitimate heir to Camelot.
Johnson framed the exclusion in general terms. He announced that no member of his government, or anyone who regularly attended its meetings, would be considered for the vice presidency, wording aimed specifically at Kennedy while presented as a general rule. Kennedy's documented reaction to the meeting came through information his friends later provided to White. He had indeed come to the Oval Office at one o'clock, and the president sat behind his desk. The business portion took only a few minutes of the 45-minute session. The president looked at the wall, then at the floor, then said he was thinking about the vice presidency in terms of what was best for the country, the party, and himself.
Kennedy left the meeting and later told his aides, "Johnson was very nice about using the knife." That documented line reveals everything about how Robert Kennedy took what happened. He knew what Johnson had done. He acknowledged it with grim precision, and he gave the public nothing.
The broader surveillance dimension of the Johnson-Kennedy relationship includes Johnson's documented use of the FBI's political intelligence operations, though the evidence establishes Johnson's reporting system and the bureau's wider operations, not that Johnson specifically ordered wiretaps on Kennedy's calls. The Senate intelligence committee investigation, whose findings Time magazine published in its coverage of the Church Committee, documented what Johnson did with the bureau during his presidency.
Through the bureau's political intelligence operations, Johnson asked Hoover to assign a special 31-member detail to the 1964 Democratic National Convention in Atlantic City, ostensibly to detect any agitators. That detail, sent without Robert Kennedy's knowledge, provided immediate reports to Johnson's aides on party conflicts at the convention. This matters. The FBI was nominally under the attorney general's authority. Robert Kennedy was the attorney general. The special detail was sent without his knowledge.
Johnson was using the FBI, the agency Kennedy technically led, to gather political intelligence at a convention where Kennedy's political future was being decided. Kennedy was excluded from his own party's security apparatus while that apparatus reported to his rival.
The relationship between Johnson and J. Edgar Hoover is central to understanding the intelligence dimension of the Johnson-Kennedy conflict. Hoover and Robert Kennedy had a famously hostile relationship. When Kennedy became attorney general, he treated Hoover, technically his subordinate, with a sharp, practical style that infuriated the director. Kennedy bypassed Hoover's secretary and walked directly into the director's office. He installed a direct telephone line from Hoover's office to his own, bypassing the formal protocols Hoover had maintained for decades.
Hoover, who had served presidents and attorneys general for nearly four decades and had built enormous institutional power by making himself indispensable and dangerous, found in Robert Kennedy a boss he did not truly fear. After John Kennedy's assassination, Hoover called Robert Kennedy to tell him of his brother's death. He delivered the news without any condolence and in a dry, bureaucratic tone that Robert Kennedy, in his documented reaction, described as horrifying. The call, according to multiple documented accounts, was one of the coldest and most emotionally stripped notifications a man in Kennedy's position ever received.
From that moment, Hoover's institutional loyalty shifted entirely to Johnson. Johnson and Hoover were natural allies, both practitioners of raw political power, both students of how to turn information into leverage. Johnson's documented use of Hoover's intelligence apparatus was extensive.
Time magazine's documented coverage of the Church Committee findings explained how Johnson obtained political intelligence from FBI wiretaps on fellow Democrats during the 1964 Democratic National Convention. During the 1964 campaign, Johnson asked his aide Bill Moyers to have the FBI run checks on the Senate staff of Republican nominee Barry Goldwater. Hoover's men conducted checks on 15 of them. Johnson also requested FBI checks on at least seven journalists who displeased him.
Furthermore, Hoover himself told Robert Mardian in 1971 that the FBI, on direct orders from the Oval Office, had placed listening devices on Goldwater's campaign plane in 1964. When Mardian asked Hoover why he complied with such a flagrantly illegal order, Hoover said simply, "You do what the president of the United States tells you."
Time's documented account of Johnson's relationship with Hoover describes Johnson's hunger for information in vivid terms. He once boasted that he knew within minutes what Senator William Fulbright, then chairman of the Foreign Relations Committee, had said during a lunch at the Soviet embassy. He slapped his thigh with delight when he received an FBI report about a prominent Republican senator frequenting a selected brothel in Chicago.
As the 1968 Democratic convention approached, the FBI was sending Johnson near-daily reports on people and events in that turbulent period. One of Johnson's aides recalled that the reports included information on the activities of members of Congress and the Senate. Robert Kennedy was now one of those senators.
After resigning as attorney general in September 1964 to run for the Senate from New York, Kennedy was no longer Johnson's nominal subordinate in the bureau's chain of command. He was now among the political figures whose activities Hoover tracked, and whose information Johnson consumed.
A Johnson recording from December 1966, classified by the Miller Center, documents a conversation between Johnson and Clark Clifford in which Clifford's meeting with an unnamed man about the dispute between Robert Kennedy and J. Edgar Hoover over bureau wiretaps was discussed. The recording also refers to Robert Kennedy's concerns about Senator Edward Long's hearings on surveillance.
This is a documented moment in which the question of surveillance—what information is gathered, who gathers it, and for what purpose—was discussed at the highest levels of the Johnson White House, specifically in the context of the dispute between the two men. Kennedy's concerns about the Long hearings are significant. Senator Edward Long of Missouri was holding Senate hearings on federal wiretapping and surveillance practices. Those hearings threatened to expose the full scope of FBI surveillance operations, including operations authorized under Kennedy and continued under Johnson.
Robert Kennedy had himself authorized wiretaps during his time as attorney general—on journalists, and on Stanley Levison as part of the surveillance surrounding Martin Luther King Jr. and others. His own record on surveillance was complicated. The Senate intelligence committee later found that Robert Kennedy had signed or authorized wiretap orders on at least six Americans other than journalists, including executive branch officials and foreign lobbyists.
That complexity is essential to understanding Robert Kennedy's documented behavior regarding Johnson's recording practices. Kennedy was not in a position to make surveillance the centerpiece of his opposition to Johnson, because his record as attorney general included authorized surveillance operations. What he could do, and what the documented record shows he did, was protect himself operationally. He was careful in meetings he knew were recorded. He kept sensitive communications on channels he trusted. He chose his words in Oval Office meetings with the awareness that Johnson recorded everything.
The documented dispute between Kennedy and Hoover, which Johnson's December 1966 recording refers to, was a public dimension of this broader tension. Hoover made statements to journalists that were published in newspapers, questioning Robert Kennedy's account of various decisions made during his tenure as attorney general. Kennedy said, for example, that he had not been informed of certain FBI surveillance operations involving Martin Luther King Jr. Hoover contradicted this flatly in press statements, presenting documents he claimed proved Kennedy was fully aware. The Church Committee later found, regarding the placement of certain microphones in King's hotel rooms, that there was no evidence Kennedy was informed of them or knew they existed.
But the public dispute between Hoover and Robert Kennedy over surveillance—who gave the orders, who knew, who was responsible for the operations—was a documented and ongoing battle throughout 1966 and 1967. Johnson watched this dispute with feelings his aides described as complicated. On one hand, he benefited from anything that damaged Robert Kennedy's reputation or distracted him. On the other, Johnson had documented concerns about Hoover's independence and unpredictability.
Johnson's December 1966 recordings, in which Clifford discusses the Kennedy-Hoover dispute, also include a reference to the weakness of Johnson's influence over Hoover. Johnson had inherited Hoover, just as he had inherited everything else from the Kennedy administration. And Hoover, who had outlasted eight presidents, was never fully under anyone's control.
What Robert Kennedy did, when confronted with the fact that Johnson's recording system was running and that Hoover had shifted his loyalty to Johnson, was exactly what a man with his experience and intelligence would do. He became careful. He grew more reserved, and he began to document meetings he knew were recorded. He maintained a public appearance of cooperation while building his political base in New York. He won the Senate seat that gave him the independent platform he needed to eventually challenge Johnson directly.
When Robert Kennedy challenged Johnson publicly and politically, first through his criticism of the Vietnam War in 1967, and then through his presidential campaign in 1968, he did so from a documented position of strength. He held a Senate seat. He held public prominence. He held the loyalty of a large part of the Democratic coalition. He had been careful not to give Johnson anything that could be used against him in the sensitive conversations that mattered to their political conflict.
The restraint Robert Kennedy showed in July 1964, when he saw the recorder running and adjusted his behavior accordingly, was not weakness. It was the conduct of a man who understood the system he was operating within—who had used that same system himself when he ran it, and who knew that the only way to survive was to never give your opponent something you were not prepared to hear quoted back at you.
