Canuck Letter

The Canuck Letter was a fabricated attack on Edmund S. Muskie, and one of the clearest concrete examples The Washington Post could offer of political sabotage connected to Richard Nixon’s reelection effort. Its importance grew through a sequence of disclosures and denials: White House aide Kenneth Clawson privately claimed authorship to reporter Marilyn Berger, the paper recorded her account, and its investigation placed the letter within a broader campaign of spying and disruption directed at Democratic contenders.

Identity and Political Purpose

The evidence identifies the Canuck Letter as a letter targeting Muskie, then a prominent Democratic presidential contender. The book does not reproduce its text or specify every claim it contained; its account instead centers on the letter’s authorship, intended political effect, and place within the larger operation. In her account of a conversation with Clawson, Berger recorded that he said he had written the letter and explained that Muskie was the candidate they considered the strongest opposition and wanted removed from contention. Clawson also indicated that Muskie’s reaction had exceeded what they expected.

This purpose made the letter more than an isolated falsehood. It was described as a political dirty trick aimed at weakening an opposing candidate, and it later served as hard evidence for the reporters’ broader account of sabotage. The distinction matters: the letter itself supplied a specific example, while the investigation’s account of a nationwide operation depended on many strands of evidence beyond this one act.

Berger’s Account of the Confession

Berger’s record of the disclosure was unusually particular. On the evening of September 25, 1972, at about 8:30, Clawson telephoned her at her apartment and invited her for a drink. She accepted after declining similar invitations from him twice in earlier weeks. In the conversation, they discussed reporting and government work. Clawson told her that reporters knew only a fraction of what happened inside government; when the discussion turned to the letter, he said he had written it. Berger recorded that she was shocked and asked why he had done so. His explanation, as she reported it, was that Muskie represented the strongest opposition and that they wanted him out.

Berger also noted that Clawson treated the act as politics rather than as the kind of dishonest conduct he had practiced as a reporter. She recorded his praise of Richard Nixon during the same conversation, but the evidentiary significance of her memo rests most directly on its account of the authorship claim and the motive Clawson gave. The memo preserved not merely a later newsroom recollection but a detailed account Berger filed after the conversation, identifying its time, setting, and the substance of what she said Clawson had told her.

From Private Claim to Public Dispute

When Berger told Bernstein that Clawson had admitted writing the Canuck Letter, the news spread through the newsroom. Editors decided that she should meet Clawson again and see whether he would repeat himself. At lunch at Sans Souci the next day, Berger told him that Woodward and Bernstein were investigating a larger story, had traced the letter to the White House, and had been told by her that he claimed to have written it. Clawson appeared serious and said he wished she had not told them. He then challenged the possibility that the reporters could have traced the letter to the White House and insisted he would deny his authorship. He asked what evidence they had; Berger answered cautiously and vaguely, without claiming to know the full investigative record.

The exchange exposed the gap between a private admission and a public account. Berger had a specific, contemporaneously recorded attribution, while Clawson’s later position was denial and skepticism about what the reporters could prove. Her lunch memo preserved that reversal as well as the earlier claim. The Washington Post’s eventual story reported both that Clawson had told Berger he wrote the letter and that he denied it. The paper thus made the contradiction part of the published account rather than presenting the confession as uncontested fact.

The Letter in the Investigation

The Canuck Letter became central to a story whose opening made a much wider claim: that the Watergate bugging had grown out of a large campaign of political spying and sabotage conducted for Nixon’s reelection and directed by White House and Committee for the Re-election of the President officials. The reporters regarded the broad interpretation as risky. No source had explicitly told them that federal investigators had reached precisely that conclusion; instead, they assembled information in investigative files, statements from multiple sources, deductions, and evidence accumulated over months. In that context, the letter and Donald Segretti’s activities were among the story’s concrete examples supporting its characterization of the campaign.

The published article gave the letter substantial room. After the opening and the response from the campaign organization, ten paragraphs dealt with the Canuck Letter, recounting Clawson’s reported statement to Berger and his denial. The account of Segretti appeared later in the article, and the story’s description of at least fifty undercover Nixon operatives traveling around the country to disrupt and spy on Democratic campaigns appeared farther inside. This placement made the letter an early, tangible instance of the conduct behind the larger thesis, without making it the sole proof of a nationwide operation.

Consequences and Significance

The letter helped bring the White House connection closer to the center of the Watergate investigation. After the reporting linked the broader operation to White House officials and campaign workers, the White House chose The Washington Post as a target even though Time had developed information it considered similarly damaging. The public clash over the paper’s reporting gave its allegations greater currency. Soon afterward, The New York Times published telephone-record evidence showing that a phone or credit card used by Segretti had been used for calls to the White House, Dwight Chapin’s home, and Howard Hunt’s home and office. Those records documented links in the wider investigation; they were not, by themselves, proof of who wrote the Canuck Letter.

The eventual public acknowledgment that the paper had been right came in a different form. After Nixon’s April 30 address, press secretary Ronald Ziegler apologized to The Washington Post and its reporters for earlier criticism of their Watergate reporting, saying that mistakes had been made and that the White House had been wrong in that instance. That apology concerned the paper’s investigative work as a whole, not a separate adjudication of the letter’s authorship. The Canuck Letter’s lasting role in the account is more precise: Berger’s report of Clawson’s claim, his subsequent denial, and the paper’s careful publication of both made the letter a documented example through which readers could see how an individual political trick connected to a larger campaign—and how that connection became a public contest over evidence.
