The Watergate Scandal

Overview

The Watergate scandal ran from the June 1971 Pentagon Papers leak to the January 1975 convictions of Nixon's closest aides, ending in his resignation on 9 August 1974 — the only resignation of a sitting U.S. president. Event text follows the source review closely; a few known date, number, and spelling corrections are flagged inline, with the full list in the review notes doc.

The New York Times began publishing excerpts from a 47-volume classified Defense Department study of U.S. decision-making in Vietnam, leaked by former military analyst Daniel Ellsberg. It revealed that several administrations had misled the public about the war's progress and chances of success — a breach the Nixon White House treated less as a policy embarrassment than as a dangerous precedent about controlling secrets.

That reaction is what makes this the real starting point of Watergate. The alarm over this leak is what drove the White House to create its own leak-plugging unit weeks later, setting the whole chain of events in motion.

White House aides David Young and Egil Krogh drafted a memo arguing the administration needed its own unit to stop leaks like the Pentagon Papers, since Nixon didn't trust the FBI or CIA to pursue it aggressively enough. The unit took its name from its job — plugging leaks — and formally stood up three weeks later, on July 24, under Krogh, Hunt, and Liddy, supervised by Ehrlichman.

The Plumbers mattered because they normalized off-the-books operations answerable only to the White House. The same people and mindset carried directly into the Ellsberg break-in that September and, less than a year later, into the plan to bug the DNC's offices — making the Plumbers less a side story than Watergate's institutional origin.

E. Howard Hunt, a former CIA officer, is brought onto the White House staff, appointed by Charles Colson and John Ehrlichman. His first assignment will be a break-in at the office of Daniel Ellsberg's psychiatrist.

President Nixon authorises White House Special Investigations Unit, Egil Krogh, Gordon Liddy, Howard Hunt and David Young supervised by Erlichman '...purpose to stop security leaks and investigate other sensitive security matters' (Pres. Nixon)

Nixon aides begin compiling a White House "enemies list," intended, in one participant's words, "to use the available federal machinery to screw our political enemies."

The Plumbers burglarize the Beverly Hills office of Dr. Lewis J. Fielding, the psychiatrist of Daniel Ellsberg, the analyst who leaked the Pentagon Papers. The break-in yields nothing usable, but evidence of it later surfaces and causes a judge to dismiss all charges against Ellsberg.

At a meeting in Key Biscane, John Mitchell and Jeb Magruder discuss Liddy's plan to bug telephone of Larry O'Brien. Mitchell quoted by Magruder as saying "O.k., let's give him (Liddy) $250,000".

Liddy asks campaign treasurer Hugh Sloan for $83,000. Most of it will end up buying surveillance equipment for James McCord.

Liddy passes $65,000 of that money to McCord. By June 17, McCord will have received $76,000 in total for the operation.

J. Edgar Hoover, FBI director for nearly half a century, dies. L. Patrick Gray is named Acting Director — a distinction that matters later, since his nomination to the permanent post is withdrawn the following year.

A first break-in attempt at the DNC's offices in the Watergate complex fails when the team cannot force open the stairwell door.

A second attempt fails the next night for the same reason: they cannot pick the lock.

A third attempt succeeds. McCord, Barker, Martinez, Gonzalez and Sturgis get inside, photograph documents, and install wiretaps, then celebrate afterward with Hunt and Liddy, the operation's organizers.

The team returns to service the wiretaps, but a 24-year-old night guard, Frank Wills, notices for the second time that night that a stairwell door latch has been taped to keep it from locking. He calls the police, and McCord, Barker, Sturgis, Gonzalez and Martinez are arrested inside the building. Within hours, back at the White House, Jeb Magruder is already on the phone asking an assistant to clear potentially incriminating files out of his office — the first move in a two-year cover-up.

The Washington Post reports that James McCord was on the payroll of Nixon's re-election committee, and Hunt's name turns up in the address book of burglar Bernard Barker. The White House's story about Hunt shifts within hours — consultant, then not, then terminated months earlier. Meanwhile Counsel John Dean orders documents removed from Hunt's White House safe, files Magruder had pulled are quietly returned to him (an aide later testifies he believes they were destroyed), and Dean privately warns Attorney General Richard Kleindienst that "this matter could lead directly to the White House."

Dean examines the contents of Hunt's safe and finds a forged diplomatic cable and files on the Pentagon Papers and Ellsberg. He later testifies that Erlichman told him to destroy them.

Gordon Liddy tells campaign officials Frederick LaRue and Robert Mardian that the arrested men will need money for bail and their families; Mardian calls it blackmail and argues against paying. The same day, Magruder warns Sloan he may have to perjure himself about how much money Liddy received.

Alfred Baldwin, a lookout who monitored the wiretaps from a nearby hotel, begins cooperating with investigators to avoid prison — the first crack in the burglars' unity.

John Dean asks the CIA's Vernon Walters for money to help the burglars. Walters refuses, later saying he told Dean the agency had no involvement in the burglary and would not fund anyone's defense.

Magruder asks campaign aide Bart Porter to back up a cover story — that $100,000 given to Liddy had been for something "more legitimate-sounding than dirty tricks." Porter agrees.

Dean tells Nixon's personal attorney, Herbert Kalmbach, that the burglars need money. Finance chairman Maurice Stans gives Kalmbach $75,000, which he distributes as $40,000 to Hunt's wife Dorothy and $25,000 to attorney William Bittman — the first installment, by one account, of roughly $500,000 that eventually reaches the defendants and their lawyers.

LaRue advises Hugh Sloan to resign rather than perjure himself or take the Fifth Amendment. Sloan resigns the next day.

Another $40,000 moves from LaRue through Kalmbach to Anthony Anthony Ulasewicz, the courier who physically delivers much of the hush money.

Newsday reports that Liddy sacked because he refused to co-operate with FBI.

The Washington Post reports that a $25,000 check meant for the re-election committee has turned up in one of Barker's bank accounts.

Finance chairman Stans denies that any campaign contribution financed the break-in. The denial collapses the very next day, when campaign official Clark MacGregor admits Liddy did give Barker that $25,000 check — the first public confirmation that campaign funds paid for the burglary.

Coached by John Dean, Magruder commits perjury before the grand jury.

Nixon is renominated for president at the Republican National Convention, 1,347 votes to 1, the scandal still largely hidden from the public.

Kenneth Dahlberg testifies that he gave Barker a $25,000 check, though he cannot explain how Barker ended up with $114,000 in campaign funds altogether.

The Government Accountability Office refers violation of new Federal Election Campaign Act by FCRP to Justice Department. Violations involving upto $350,000, including $114,000 found in burglar Barker's account.

Kleindienst said investigation will be "the most extensive since the assassination of President Kennedy".

President Nixon announces that John Dean has carried an investigation into Watergate. "I can state categorically that his investigation indicates that no one in the White House Staff, no one in this administration,...was involved in this very bizarre incident". Later this report is denied by Dean, who claims that this was the first he had heard of it.

A federal grand jury indicts Frank Sturgis, Virgilio Gonzales, Eugenio Martinez, Bernard L. Barker, James W. McCord, E. Howard Hunt and Gordon Liddy — a group the press dubs the "Watergate Seven." (A second, unrelated group would be indicted under the same nickname eighteen months later for the cover-up itself.) The Justice Department states it has "absolutely no evidence to indicate that any others should be charged."

Ulasewicz delivers $53,000 to Dorothy Hunt and $29,000 to Frederick LaRue.

Woodward and Bernstein claim Operation Gemstone - intelligence gathering for the Republican party - was financed by a fund controlled by John Mitchell (Attorney General at the time).

The reporters' source — known only as "Deep Throat," and publicly identified only in 2005 as FBI Associate Director W. Mark Felt — tells Bernstein that the sabotage of Senator Edmund Muskie's campaign was a White House operation.

Woodward and Bernstein report Donald Segretti was being paid $20,000/year to sabotage Democrat campaign.

Seymour Hersh reports in NY Times on phone calls between Segretti and Hunt.

'Deep Throat' tells Woodward that H. R. Haldeman is a major figure in the cover-up.

Acting under doctor's orders, Judge Sirica postpones Watergate trial until January 8th, 1973.

Nixon defeats George McGovern. Elected with largest plurality of votes in American history. He captured 60.8% of the popular vote and 97% of the electoral vote.

Donald Segretti tells Carl Bernstein that Hunt and Liddy are behind dirty tricks against Democrats.

Hunt asks Colson for more money by 25th November 1972.

Nixon, Colson, Haldeman, and Erlichman meet at Camp David to discuss Hunt's 'blackmail' attempt.

Nixon demands resignation of Director of CIA, Richard Helms.

John Mitchell tells John Dean to give a part of $350,000 (kept in Hugh Sloan's office) to Hunt. Money is given to Frederick LaRue to organise transfer.

Judge declares a mistrial of Pentagon Papers trial due to the four month time lapse between seating of jury and start of trial.

Hunt's wife, Dorothy, dies in plane crash. her pocket book containing$10,000 in $100 bills is recovered.

Dean and Ehrlichman gave FBI chief L. Patrick Gray sensitive documents from Hunt's safe, telling him to make them disappear. Gray burned them at home with the Christmas trash on December 25, 1972. The act came out in April 1973, forcing his resignation.

Trial of 7 burglars begins in Washington, under Judge John J. Sirica. Liddy and McCord convicted after trial, other 5 plead guilty.

Hunt takes an anonymous call in a pay phone near his home. He is told "A year is a long time. Your wife and family will be taken care of. You will be rehabilitated with employment when this is over". Dean told Caulfield to have this message delivered. Caulfield got Ulasewicz to do it.

Hunt promises burglars that they, and their families, will be looked after if they plead guilty.

Hunt pleads guilty. The same day, Senator Sam Ervin agrees to chair the Senate's investigation into Watergate.

Senator Sam Ervin agrees to head up the Senate's investigation of Watergate.

McCord and Liddy convicted of conspiracy, burglary and wiretapping at Watergate..

Sturgis, Gonzalez, Martinez and Barker plead guilty. They deny being threatened into such a plea.

Ellsberg and Russo's retrial on Pentagon Papers espionage charges opened in Los Angeles on January 19, 1973, after their first trial ended in mistrial. It would later collapse in May 1973 when the judge dismissed all charges over government misconduct, including the Plumbers' break-in at Ellsberg's psychiatrist's office.

On January 23, 1973, Jeb Magruder testified that roughly $235,000 in campaign funds had been funneled to Gordon Liddy, characterizing the payments as support for "intelligence operations" rather than admitting to their true purpose funding the Watergate break-in and related espionage activities. His account echoed Hugh Sloan's testimony the same day that Mitchell and Stans had approved similar payments, though the vague "intelligence" framing was widely seen as an effort to obscure the money's actual criminal use.

Sloan testifies that Mitchell and Stans approved payment to him of $199,000, which Magruder directed him to give to Liddy.

On January 24, 1973, Deep Throat told Woodward that Colson and Mitchell were the figures behind the Watergate operation, pointing to direct involvement from both the White House and the campaign leadership rather than a rogue effort by lower-level operatives. The tip pushed Woodward and Bernstein's reporting further up the chain of command, reinforcing the emerging picture that the break-in had been authorized at senior levels rather than being an isolated act by Liddy and the burglars.

CRP (Committee for the Re-Election of the President) is fined $8,000 for 8 campaign violations, including failure to report money given to Liddy by Sloan.

Senate votes 70 - 0 to set up a Select Committee on Presidential Campaign Activities, under Sam Ervin.

Dean later testifies that today he told the President of his own role in the cover-up. He alleges that the President said "not to worry".

During hearings, Gray reveals he provided John Dean with daily updates on Watergate intelligence. And that Dean had probably lied to FBI investigators.

Nixon issued a policy statement asserting that his staff would "normally decline" requests to testify before Congress, invoking executive privilege to shield aides from the Senate's Watergate inquiry. The move was widely seen as an attempt to prevent key witnesses like Haldeman, Ehrlichman, and Dean from being questioned under oath about the cover-up.

McCord writes to Judge Sirica claiming guilty pleas made under pressure from Dean and Mitchell and that burglary was not a CIA activity.

Fred LaRue delivered another $75,000 payment to Hunt, continuing the pattern of hush money channeled to the Watergate defendants to keep them silent. The payment came amid mounting pressure, just a day after McCord's letter to Judge Sirica alleging he had been coerced into pleading guilty by Dean and Mitchell.

The payment came amid mounting pressure, just a day after McCord's letter to Judge Sirica alleging he had been coerced into pleading guilty by Dean and Mitchell.

McCord testifies that he was told by Liddy Watergate had been approved by Mitchell while he was still Attorney General.

White House Counsel, John Dean, agrees to co-operate with Watergate prosecutors.

Jeb Magruder claims Dean and Mitchell organized the bugging and payoff scheme.

Nixon issued a public statement insisting he had no prior knowledge of the Watergate break-in or the cover-up that followed it. The claim came just days after Magruder implicated Dean and Mitchell in the bugging and payoff scheme, and only three days before Dean himself would begin cooperating with prosecutors, making Nixon's denial increasingly difficult to sustain.

The NY Daily News reports that Gray destroyed documents from Hunt's White House safe, including fabricated cables implicating President Kennedy in Ngo Ngo Dinh Diem's assassination and other files concerning Edward Kennedy; Gray later admits it.

Gray resigns after exposure of destroying Hunt's files. New FBI director is to be William Ruckelshaus

'Deep Throat' confirms story about Gray destroying documents. Says that Erlichman and Dean gave instructions for document disposal.

Nixon purged his inner circle, dismissing White House Counsel John Dean while accepting the resignations of his top aides H.R. Haldeman and John Ehrlichman. The dramatic shakeup, announced in a televised address, marked Nixon's attempt to distance himself from the scandal even as it signaled how deeply the cover-up had reached into his closest advisors.

On May 17, 1973, the Senate Watergate Committee, chaired by Sam Ervin, opened its televised hearings into the break-in and subsequent cover-up. The proceedings would captivate the nation over the following months, drawing testimony from key figures like Dean, Magruder, and eventually revealing the existence of Nixon's secret taping system.

Archibald Cox appointed to investigate possible presidential impropriety.

On June 3, 1973, John Dean told investigators that Nixon had personally participated in the Watergate cover-up, recalling at least 35 conversations between them on the subject. Dean went further still, floating the possibility that Nixon had been secretly recording their discussions all along — a suspicion that would prove prophetic weeks later.

Nixon flatly rejected the Senate Watergate Committee's requests, declaring he would neither testify himself nor turn over presidential documents for the investigation. The refusal set up a direct confrontation between the White House and Congress, foreshadowing the executive privilege battles that would soon engulf the tapes themselves.

Alexander Butterfield, former presidential appointments secretary, tells committee that all conversations and phone calls have been taped since 1971.

Nixon orders White House taping system disconnected.

On July 23, 1973, just ten days after Alexander Butterfield revealed the existence of Nixon's secret White House taping system, both special prosecutor Archibald Cox and Senate Watergate Committee chairman Sam Ervin formally demanded that Nixon turn over a specific set of tapes and documents relevant to their parallel investigations. The demands sought recordings of conversations directly tied to the break-in and cover-up, aiming to verify or refute the testimony already given by Dean and other witnesses. Nixon's response two days later, flatly refusing to comply, set off the executive privilege fight that would eventually reach the Supreme Court in the following year's landmark ruling.

On July 25, 1973, Nixon refused to hand over the tapes and documents demanded by both the Senate committee and Cox, citing executive privilege. The standoff escalated the constitutional fight between the presidency and the other two branches, foreshadowing the Saturday Night Massacre that October.

On August 15, 1973, with Nixon still refusing to comply with their July demands, Cox and Ervin escalated the fight by asking the Supreme Court to directly order the President to hand over the disputed tapes. The move set the stage for a landmark constitutional showdown over executive privilege, one that would culminate almost a year later in the Court's unanimous ruling against Nixon.

On October 10, 1973, Vice President Spiro Agnew pleaded no contest to federal tax evasion charges tied to a separate kickback scandal and resigned as part of the plea deal. Though unrelated to Watergate, the resignation compounded the administration's crisis, forcing Nixon to name Gerald Ford as his replacement just two days later.

Gerald Ford nominated by President Nixon as Vice-President.

On October 20, 1973, Nixon ordered Cox fired; Elliot Richardson refused and resigned, William Ruckelshaus refused and was fired, and acting Attorney General Robert Bork finally carried out the dismissal. The "Saturday Night Massacre" sparked national outrage and intensified calls for impeachment.

On October 23, 1973, in the face of intense public backlash following the Saturday Night Massacre, Nixon reversed course and agreed to comply with the subpoenas by releasing some of the White House tapes, rather than continuing to fight the courts over executive privilege. The concession came just three days after firing Cox and briefly eased the immediate pressure, though it did little to quell the growing momentum toward impeachment, as questions remained over which tapes would actually be handed over and whether they were complete.

On November 1, 1973, amid the public firestorm following the Saturday Night Massacre, Leon Jaworski was appointed as the new special prosecutor, replacing the fired Archibald Cox. To help restore confidence after the controversy, Nixon granted Jaworski stronger assurances of independence than Cox had received, including that he could only be dismissed with the agreement of congressional leaders — safeguards that would prove significant as Jaworski went on to press the fight for the tapes all the way to the Supreme Court.

On November 17, 1973, facing questions about his personal finances and tax returns, Nixon told a convention of newspaper editors at Disney World, "People have got to know whether or not their President is a crook. Well, I'm not a crook." The line became one of the era's most enduring — and ironic — soundbites.

Watch the clip here.

On November 21, 1973, an 18-and-a-half-minute gap was discovered in a Nixon-Haldeman tape recorded just days after the break-in. Nixon's secretary, Rose Mary Woods, admitted causing part of the gap by accident but denied deliberately erasing it — a mystery that fueled suspicions of a cover-up and was never fully resolved.

On January 28, 1974, Herbert Porter, a scheduling aide for Nixon's re-election campaign, pleaded guilty to perjury for lying to investigators about the campaign's finances. Porter's false testimony traced back to June 1972, when Jeb Magruder had asked him to corroborate a cover story that $100,000 given to Liddy was for legitimate purposes rather than the dirty tricks operation it actually funded, and Porter had agreed to go along with it. His guilty plea was among the earliest signs that the wall of loyalty among Nixon's inner circle was beginning to crack under the weight of the ongoing investigations.

On February 6, 1974, the full House of Representatives voted to formally authorize the House Judiciary Committee to investigate whether sufficient grounds existed to impeach President Nixon. This gave the committee, chaired by Peter Rodino, broad subpoena power to compel testimony and documents as it built its case, marking the first formal step in what would become the constitutional process to remove Nixon from office. The investigation would run for several months, culminating that summer in the committee's vote to approve articles of impeachment.

On February 25, 1974, Herbert Kalmbach, Nixon's personal attorney and campaign fundraiser, pleaded guilty to two charges of illegal campaign activities, including selling ambassadorships for contributions. Kalmbach had earlier helped funnel hush money to the Watergate defendants, and his plea added another senior Nixon insider to the growing list of convictions.

On March 1, 1974, a federal grand jury indicted seven of Nixon's top aides — Mitchell, Haldeman, Ehrlichman, Colson, Mardian, Parkinson, and Strachan — on conspiracy charges tied to the Watergate cover-up.

The same grand jury secretly named Nixon himself an unindicted co-conspirator. The indictments tied the administration's most senior officials directly to criminal conduct just as the House impeachment inquiry was gaining momentum.

On April 5, 1974, Dwight Chapin, Nixon's former appointments secretary, was convicted of perjury for lying about his role in recruiting Donald Segretti to run the campaign's "dirty tricks" operation against Democratic candidates. The conviction extended the scandal beyond the break-in itself into the broader pattern of political sabotage first exposed by Woodward and Bernstein.

On April 30, 1974, Nixon released over 1,200 pages of edited, heavily redacted tape transcripts in a televised address, hoping to avoid surrendering the actual recordings. The House Judiciary Committee rejected the substitute, insisting on the unedited tapes — a standoff resolved only when the Supreme Court ordered Nixon to comply that July.

On June 15, 1974, Woodward and Bernstein published "All the President's Men," detailing their investigative reporting on the cover-up for The Washington Post. The book, released just weeks before Nixon's resignation, became a landmark of journalism and later an Academy Award-winning film.

On July 24, 1974, the Supreme Court ruled unanimously, 8–0, in United States v. Nixon that the President must comply with the special prosecutor's subpoena and turn over the White House tapes for use in the Watergate defendants' trials. The Court rejected Nixon's claim of absolute executive privilege, holding that it did not outweigh the fundamental need for evidence in a criminal proceeding. The ruling was a decisive legal blow, leaving Nixon with no further grounds to withhold the recordings — among them the "smoking gun" tape that would surface less than two weeks later and precipitate his resignation.

On July 27, 1974, the House Judiciary Committee voted 27–11 to approve the first article of impeachment against Nixon, charging him with obstruction of justice for his role in the Watergate cover-up. The bipartisan vote included six Republicans breaking ranks to support the article, signaling that Nixon's support was crumbling even within his own party. Two more articles, covering abuse of power and contempt of Congress, would follow in the days after, setting the stage for a full House vote that never happened once Nixon resigned that August.

On August 5, 1974, Nixon released transcripts of a tape recorded on June 23, 1972 — just six days after the break-in — that became known as the "smoking gun" tape. In it, Nixon is heard directing Haldeman to have the CIA pressure the FBI into halting its investigation of the burglary by falsely claiming it involved national security matters, direct proof that Nixon had personally ordered the cover-up almost from the very start. The revelation destroyed his remaining political support, including among the Republicans who had defended him, and within days the leadership of his own party told him impeachment and removal were now inevitable, prompting his resignation just three days later.

Listen to "The Smoking Gun Tape".

On the evening of August 8, 1974, Nixon addressed the nation in a televised speech announcing that he would resign the presidency effective noon the following day, becoming the first and only U.S. president to do so. He framed the decision as being in the national interest rather than an admission of guilt, saying he no longer had "a strong enough political base" to continue governing effectively after the "smoking gun" tape had eliminated any remaining support in Congress. Vice President Gerald Ford was sworn in as president on August 9, 1974, telling the country in his own address that "our long national nightmare is over," and just a month later would grant Nixon a full pardon for any crimes committed during his presidency.

On September 8, 1974, just a month after taking office, President Gerald Ford granted Nixon a "full, free, and absolute" pardon covering any federal crimes he may have committed during his presidency, from January 20, 1969 through August 9, 1974. Ford framed the decision as necessary to end the national trauma of Watergate and allow the country to move forward, rather than see a former president dragged through a lengthy criminal trial. The pardon proved deeply controversial, fueling suspicions of a secret deal between Ford and Nixon and contributing to a sharp drop in Ford's approval ratings, though it also meant Nixon was never formally convicted of any Watergate-related crime.

On January 1, 1975, a jury convicted John Mitchell, John Ehrlichman, and H.R. Haldeman — Nixon's former Attorney General, chief domestic policy advisor, and chief of staff — of conspiracy, obstruction of justice, and perjury for their roles in the Watergate cover-up. The verdicts, reached after a lengthy trial before Judge John Sirica, marked the conclusion of the criminal prosecution of the president's closest aides, all three of whom received prison sentences. With Nixon himself shielded by Ford's pardon, these convictions represented the final and most senior reckoning of the scandal, closing the loop on a conspiracy that had reached to the very top of the administration.

On May 31, 2005, W. Mark Felt, the former Associate Director of the FBI, revealed in a Vanity Fair article that he had been "Deep Throat," the anonymous source who had guided Bob Woodward and Carl Bernstein of The Washington Post through their Watergate reporting. Woodward confirmed the identity the same day, ending a guessing game that had lasted more than three decades. Felt, then 91 and "hobbled by age and memory," never meaningfully spoke about his decision to cooperate with Woodward. He died in 2008.
