The White House plot to firebomb and break into the Brookings Institution was a proposed operation to recover classified documents believed to be in Morton Halperin’s office. John Dean learned of the scheme and helped stop it by alerting John Caulfield, who took the matter to John Ehrlichman. The plan never came off, but its proposed use of a firebomb made the episode a stark measure of the White House’s willingness to contemplate criminal methods—and of the intervention required to halt them.

Background and Intended Target

In the first week of June, Bernstein asked a source he had not spoken with for several weeks whether there had been any other burglaries. The answer was that one had been proposed, although the source did not think it had been carried out: the Brookings Institution, with John Dean said to have turned it off. The account therefore began with an important qualification. The reported operation was a proposal, not a completed break-in, and the source’s initial description left the method and purpose to be established.

Dean’s associate pushed back when Bernstein raised the account. He suggested that the word burglary might be wrong and described Charles Colson as wanting to start a fire. When Bernstein tested whether that meant Colson wanted to set one deliberately, the associate confirmed that it did. The euphemistic formulation did not make the proposal less serious: it pointed toward a fire as a means of enabling entry rather than an ordinary attempt to steal documents.

The reported target was Halperin’s office. Halperin, a friend of Daniel Ellsberg, had been among those whose telephones were tapped during Henry Kissinger’s leak investigation. The White House believed that Halperin had kept classified documents after leaving Kissinger’s staff to become a fellow at the Brookings Institution, a center for public-policy research. The stated aim of the operation was to retrieve those papers. According to Dean’s associate, security at the institution was too tight for the White House to risk a straightforward burglary; a fire could provide cover for breaking in.

The Intervention That Stopped It

John Caulfield’s reaction conveyed the proposal’s urgency. The associate said Caulfield ran out of Colson’s office in a panic and went directly to Dean, saying he wanted nothing more to do with Colson and that Dean had to stop him before it was too late. Dean then took the first courier flight to San Clemente to see Ehrlichman. The account presents a chain of intervention: Caulfield carried the warning to Dean, and Dean sought out the official said to have enough influence to shut the operation down.

Ehrlichman was not pleased to see Dean, according to the account, because Dean was not supposed to know about the plan. But Dean’s arrival forced the matter into the open between them. He stayed in the room while Ehrlichman telephoned Colson and instructed him to stop. Throughout the call, Ehrlichman glared at Dean as though he had betrayed him. That detail makes the intervention more than a simple exchange of orders: Dean’s presence was treated as a breach of the expected chain of knowledge, even as his disclosure was what enabled the proposal to be halted.

The source described Ehrlichman as the only person with enough influence to stop the operation at that point. The account does not establish that Dean or Ehrlichman had originated the plan, nor does it claim that the break-in occurred. It instead distinguishes the reported proposal from the action that followed: Caulfield warned Dean; Dean went to Ehrlichman; and Ehrlichman called Colson. In the narrative, the plot’s prevention depends on that intervention, while its seriousness is indicated by the alarm that prompted it.

Reporting and Corroboration

Bernstein sought a second account from someone who had heard the story from Caulfield. This source sharpened the description: the proposal was not merely to start a fire but to use a firebomb. The source also said that Caulfield had described the operation as having gone too far and wanting no further involvement with Colson. Both Dean and Caulfield, the source said, had told the story to investigators.

Woodward worried that the account might be a setup. Bernstein checked his sources again and consulted investigators before telling his colleague that the information was solid. That reporting sequence matters because the scheme was both extraordinary and, as presented, stopped before execution. The newspaper’s account did not rest only on the first source’s mention of a proposed burglary: Bernstein pursued the meaning of the fire, obtained a separate account of the firebombing proposal, and checked the information again before accepting it.

The disclosures also distinguish what the reporting could establish from what remained attributed to sources. The stated purpose was to recover documents the White House believed Halperin had retained; the firebomb was described as a way to cover the entry because security made a direct burglary too risky. The operation’s existence and internal handling were conveyed through people recounting what they had heard or done, rather than through a description of a completed raid. The plan’s reported cancellation is therefore central, not incidental: it defines the event as an aborted proposal and sets the limits of what the account claims happened.

Significance and Limits

The episode revealed a method more extreme than an ordinary covert entry: a firebomb was proposed to distract from a break-in at an institution where the White House believed sensitive documents could be found. It also exposed a fracture within the operation’s circle. Colson was associated with the proposal; Caulfield recoiled from it and sought help; Dean acted despite not being expected to know; and Ehrlichman used his influence to stop it. These roles do not collapse into a single account of uniform participation. The reported sequence includes both an effort to authorize a dangerous operation and resistance that prevented it from proceeding.

In the wider Watergate narrative, the plot sits alongside other efforts to retrieve or suppress politically damaging material, but the available account does not say that the Brookings proposal was carried out or that the documents were recovered. Nor does it treat the plan as an accomplished burglary. Its force lies in the distance between intention and outcome: the White House’s reported willingness to contemplate a firebombing is disclosed, while the intervention by Dean and Ehrlichman leaves the contemplated operation unrealized. The story’s procedural texture—the reporter’s challenge to a vague description, the second source’s more precise account, and Bernstein’s checks after Woodward’s warning—makes that distinction part of the evidence rather than a footnote.
