Interference in the Watergate investigation

Interference in the Watergate investigation was not a single obstruction but a chain of acts and disputed decisions that made the search for responsibility itself part of the Watergate crisis. Secret campaign funds had paid for political operations; investigators and prosecutors encountered missing or delayed evidence; and senior officials publicly defended accounts that later disclosures weakened. The record also preserves uncertainty: some allegations came from anonymous or politically connected sources, while documents and testimony provided firmer grounds for others. The distinction between evidence of contact, evidence of concealment, and proof of authorization remained central to the struggle over how far the investigation could reach.

A campaign fund behind the inquiry

The investigation’s financial trail led beyond the men arrested at the Democratic National Committee headquarters. A $25,000 cashier’s check payable to Kenneth H. Dahlberg had been deposited with four Mexican checks, bringing the total deposit to $114,000. Four days later, Bernard Barker withdrew $25,000; the remaining $89,000 was withdrawn separately. The check’s path established a concrete connection between campaign money and funds handled by one of the Watergate burglars, although the check by itself did not establish who had authorized the break-in.

The reporting then connected the operation to a special account at the Committee for the Re-election of the President. The account held more than $300,000 earmarked for sensitive political projects, and G. Gordon Liddy had received money from it. Records relating to the account had been destroyed. Hugh Sloan’s resignation was linked to his suspicions about Watergate. Taken together, these details shifted the inquiry from the question of what the arrested men had done to how a campaign-finance system had supplied the means for political activity and who had controlled its use.

Sloan described a routine that gave the fund’s authority a direct line to John Mitchell. When first approached for money, Sloan telephoned Mitchell at the United States Department of Justice; Mitchell told him to distribute it. The calls had begun in 1971. Mitchell was initially the sole person authorizing expenditures, and later delegated authority to others, including Jeb Stuart Magruder. Sloan’s account did not by itself prove that Mitchell had known of the bugging. He allowed the remote possibility that the men had spent money on unauthorized projects, though he doubted it. But the account placed campaign spending for apparently illegal activity under the authority of the sitting Attorney General, making the question of authorization impossible to confine to the burglars.

The official case and its limits

At the trial, Chief Judge John Sirica framed the unanswered questions directly: what the men had gone to the headquarters to do, whether they had been paid, who had hired them, and who had started the operation. Yet the prosecution’s opening account offered a narrower explanation. Earl Silbert said he could account for only $50,000 of the $235,000 in campaign funds delivered to Liddy in $100 bills. Relying mainly on statements by Magruder and Herbert L. Porter, he presented the money as support for legitimate intelligence gathering and argued that Liddy had acted on his own in planning and carrying out the illegal operation.

That account reproduced the campaign’s low-level explanation, already familiar to the reporters from their earlier inquiries. Woodward found its central claim implausible: a campaign would not spend $235,000 on inconsequential information readily available from the Federal Bureau of Investigation and local police without wanting to know what the money was for and what it had achieved. The discrepancy between the scale of the spending and the limited purpose alleged made the official explanation vulnerable, even as the prosecution maintained that it lacked evidence to indict anyone beyond the seven men already charged.

Silbert told Woodward and Bernstein that he expected his investigation to please no one, and stressed the evidentiary threshold required to charge people farther up the chain. His position exposed a tension rather than resolving it: the investigation could identify a substantial fund and a chain of delegated authority, yet still claim insufficient evidence for additional indictments. The trial’s account of a self-directed Liddy thus stood beside financial facts and testimony that kept the question of higher-level involvement open.

Files, delay, and competing accounts

The handling of material from Howard Hunt’s safe became a second test of the investigation’s integrity. After June 17, John Dean came into possession of the contents but waited at least seven days before turning them over to the Federal Bureau of Investigation. Hunt’s two notebooks were not included in Dean’s inventory. Prosecutors said they had first learned of the notebooks on October 11, when Hunt sought the return of property left at his office. Hunt’s attorney confirmed that the notebooks contained names and addresses that prosecutors believed might lead to other people involved in the conspiracy. Their absence raised a specific question: whether evidence that could widen the investigation had been overlooked, withheld, or lost.

President Richard Nixon announced that he would invoke executive privilege to prevent Dean from testifying at L. Patrick Gray’s confirmation hearings. Gray later told the Senators he was unalterably convinced Dean had withheld nothing from Hunt’s safe, and the White House separately asserted that Dean had turned over all its contents. Those assurances did not settle the matter. A later account from Deep Throat described a June 28 meeting at which John Ehrlichman and Dean allegedly told Gray the files were politically explosive and should never become public. According to this account, Ehrlichman had earlier urged Dean to dispose of them in the river; Gray kept them for about a week and then put them in a burn bag. Deep Throat said Gray had not been explicitly ordered to destroy the material but understood what the others wanted. The account directly conflicted with the reassuring public statements, while its precise details depended on a confidential source.

The surrounding climate made the dispute harder to dismiss as a simple filing error. Reporters heard that Dean had sat in on White House personnel interviews conducted by the Federal Bureau of Investigation and had received copies of investigative reports, troubling prosecutors. They also heard claims that Hunt and James McCord were being taken care of through the campaign or the White House, and that a judge had been approached through back channels. Those claims were attributed to a politically connected Washington lawyer, not established as findings. Their significance lies in the picture they presented of suspected pressure and privileged access, not in proving that every alleged intervention occurred.

Hearings expose the political connection

At the L. Patrick Gray confirmation hearings, Gray unexpectedly disclosed that he had turned the Watergate investigative files over to Dean and could not guarantee Dean had not shown them to Donald Segretti. The revelation changed the focus of the hearings: a proceeding about Gray’s nomination became, in effect, an inquiry into Dean’s access to the investigation. Gray offered to make the Federal Bureau of Investigation files available to Senators, but the image of the Bureau director acting as an aide to Dean had already taken hold.

The next day, Bernstein examined Dean’s handling of Hunt’s safe materials and the unlisted notebooks. Four days later, Gray’s defense of Dean and the White House’s statement that the safe contents had all been surrendered were overtaken by a document from Gray’s own responses to the Senators’ questions. The interview record showed that Herbert W. Kalmbach had said Dwight L. Chapin contacted him in 1971 about Donald Segretti’s impending release from military service and possible usefulness to the Republican Party. Kalmbach also admitted paying Segretti for undercover work on Chapin’s instructions. The document did not answer every question about who ordered the Watergate break-in, but it undermined the broader claim that the White House had no connection to political espionage.

Earlier public defenses likewise met accumulating documentation. After the connection between Segretti and Chapin became a target of reporting, the White House chose to attack The Washington Post even though Time had developed comparably damaging information. The next day, newspapers reported the White House’s anger, a response that gave the Post’s allegations additional prominence. Telephone records obtained by The New York Times then showed at least half a dozen calls from Segretti’s telephone or credit card to the White House and Chapin’s home, and at least 21 calls to Hunt’s home and office. The records did not by themselves establish the content of those calls, but made it more difficult to wave away the reported connections as hearsay.

Public scrutiny and political consequence

The dispute extended beyond the courtroom and the confirmation hearings. Democratic Party chairman O’Brien filed a $1 million civil damages suit against the Committee for the Re-election of the President, citing Colson’s potential involvement and arguing that the developing facts pointed toward the White House. His public questions about how many other attempts there had been transformed the break-in from a supposedly isolated episode into a test of the administration’s professed commitment to law and order.

After the election, the reporters encountered a mixture of fragmentary leads and institutional warning signs. They learned that a proposed White House report setting out the Watergate facts had been discarded as too risky; that some campaign workers referred to an account given to prosecutors as a cover story; and that Hunt and Liddy had belonged to the White House Plumbers, a team formed to investigate leaks. They also heard that searches had not been carried out at the homes of the five arrested burglars and that several Post journalists’ phones might have been tapped, though a paid electronic sweep found nothing. These reports varied in reliability and did not all establish official action. Collectively, they show why the reporters treated the investigation’s omissions and the administration’s control of information as subjects requiring scrutiny in their own right.

The White House’s eventual retreat in public reflected how far the evidence and the political stakes had shifted. In his April 30 address, Nixon accepted responsibility as the person at the top while announcing the resignations of H. R. Haldeman and John Ehrlichman. He praised the grand jury, prosecutors, Sirica, and a free press for bringing facts to light, while insisting there could be no whitewash. The following day, press secretary Ronald Ziegler apologized to The Washington Post and to Woodward and Bernstein for his earlier criticism, acknowledging that mistakes had been made as events developed. The apology did not resolve every disputed allegation or restore the lost evidence. It did mark a reversal: the administration that had dismissed the reporting now conceded that its attacks had been wrong, while the struggle over interference had helped make the conduct of the investigation central to the Watergate crisis.
