The Pentagon Papers (secret Vietnam study published, 1967 to 1973)

A classified 47-volume Defense Department history of the Vietnam War was leaked in 1971 and published by newspapers, the Supreme Court refused to let the government stop the presses by a vote of six to three, and the government's prosecution of the leaker, Daniel Ellsberg, collapsed in 1973 after the White House's own misconduct came out.

The record

What we checked

Sources we opened: New York Times Co. v. United States, 403 U.S. 713 (1971), via Justia (first 100,000 characters of about 116,000); Gravel v. United States, 408 U.S. 606 (1972), via Justia; the National Archives pages on the 2011 release (page and press release); the National Security Archive page with the Supreme Court argument and Solicitor General Erwin Griswold's later statement; the National Security Archive's commentary on the June 1971 Nixon tapes; a chronology of the Ellsberg trial hosted by Louisiana State University; Justia's Verdict article on the case; Wikipedia pages for the Pentagon Papers and Daniel Ellsberg; History.com; Britannica (short intro only); and the Pulitzer Prizes page. Sources we could not open: The New York Times' own interactive page (blocked), the full text of the lower-court rulings by Judges Gurfein and Gesell, Judge Byrne's dismissal order itself, and the Pentagon Papers volumes. We did not read the study. Everything below about its contents comes from secondary sources.

What the study was

• Defense Secretary Robert McNamara created the Vietnam Study Task Force on June 17, 1967. The result ran to 47 volumes, about 3,000 pages of analysis and 4,000 pages of documents, with 36 analysts (Wikipedia). The official title is "Report of the Office of the Secretary of Defense Vietnam Task Force." Leslie Gelb presented it to Defense Secretary Clark Clifford on Jan. 15, 1969 (National Archives).
• It covers U.S. involvement from the 1940s through May 1968 (Britannica; NARA parts begin at "Vietnam and the U.S. in 1940 to 1950"). The study itself stops in 1968. Some timelines run to 1975, which can only mean the end of the war, not the study.
• What it is said to show: that Presidents Truman, Eisenhower, Kennedy and Johnson misled the public about the extent of involvement, and that Johnson planned escalation in 1964 while campaigning on the opposite message (History.com; Wikipedia). Both are secondary. We have not verified these claims in the volumes themselves.

Timeline

• Oct. 1969: Ellsberg and Anthony Russo photocopy the study (Wikipedia).
• Mar. 2, 1971: Ellsberg gives 43 volumes to Neil Sheehan of The New York Times (Wikipedia).
• June 13, 1971: The Times publishes its first article. The National Security Archive tape commentary shows Nixon's first reaction was muted that day and angry by mid-afternoon after a call with Henry Kissinger.
• June 14, 1971: Attorney General John Mitchell sends a telegram asking the Times to stop; it refuses (Wikipedia; NSArchive tapes).
• June 15, 1971: Judge Murray Gurfein (S.D.N.Y.) issues a temporary restraining order (Verdict). The Justice Department sued the same day.
• June 18, 1971: The Washington Post begins publishing. Fifteen other papers follow (Wikipedia).
• June 19, 1971: Gurfein denies a preliminary injunction, finding the government had not shown vital harm; the Second Circuit then stayed his ruling and, on June 22, sent the matter back for further hearing (Verdict). The NSArchive page puts the lifting of the order on June 18, so sources differ by a day and we did not resolve it.
• June 26, 1971: Supreme Court hears argument. June 28, 1971: A Los Angeles grand jury indicts Ellsberg for theft and espionage; he had surrendered in Boston the same day (LSU chronology; Wikipedia).
• June 29, 1971: Senator Mike Gravel enters about 4,100 pages into the record of his subcommittee. The Beacon Press later publishes the "Gravel Edition" (Wikipedia; Gravel).
• June 30, 1971: The Supreme Court rules 6 to 3 for the newspapers.
• Sept. 3, 1971: E. Howard Hunt, G. Gordon Liddy and others burglarize the office of Ellsberg's psychiatrist (Wikipedia, Ellsberg).
• Dec. 29, 1971: A superseding indictment returns fifteen counts against Ellsberg and Russo (LSU chronology). Wikipedia says the maximum combined sentence was 115 years for Ellsberg and 35 for Russo; it also says Ellsberg was "charged in January 1973," which conflicts with the chronology. We use the chronology for dates.
• Jan. 17, 1973: Opening statements in the retrial after a mistrial on Dec. 12, 1972 (LSU chronology; Wikipedia gives a trial start of Jan. 3, 1973, so we are not sure which date applies to which proceeding).
• Apr. 26, 1973: Prosecutors disclose the burglary of the psychiatrist's office. May 9, 1973: the court learns of warrantless FBI wiretaps of Ellsberg's conversations with Morton Halperin that were not disclosed to the defense (Wikipedia).
• May 11, 1973: Judge William Matthew Byrne Jr. dismisses all charges. He wrote that "The bizarre events have incurably infected the prosecution of this case" and that the circumstances "offend a sense of justice" (Wikipedia; we did not read the order).
• June 29, 1972: Gravel v. United States decided.
• June 13, 2011: National Archives and the Kennedy, Johnson and Nixon libraries release the full report (press release dated June 8, 2011).

The Supreme Court ruling

The Court's unsigned opinion was short. It said the Government carries a "heavy burden of showing justification for the enforcement of such a [prior] restraint" and that it "had not met that burden." Six Justices concurred in the judgment and wrote separately. Three dissented.

At argument, Solicitor General Griswold said eleven specific items would cause "great and irreparable harm to the security of the United States" (NSArchive page, citing the transcript). In a Feb. 15, 1989 Washington Post op-ed, Griswold wrote, "I have never seen any trace of a threat to the national security from the publication" (NSArchive page; we read the quote there, not in the op-ed).

What happened to the leaker, and the Plumbers link

The White House created the "Plumbers" unit under Ehrlichman after the leak (Wikipedia). Hunt wrote a memo titled "Neutralization of Ellsberg" on June 28, 1971 (LSU chronology). The Fielding burglary was on Sept. 3, 1971. The burglars found Ellsberg's file but apparently not what they wanted (Wikipedia). Several of those same men were arrested in the DNC offices on June 17, 1972 (Case 02: Watergate). Byrne's disclosure that he had met John Ehrlichman, who raised the FBI directorship with him, is in the Wikipedia Ellsberg page; we did not read a primary source for it.

Disclosure of the study itself

In 2011 the National Archives said about 2,384 pages, or 34 percent of the 7,000-page report, were opened for the first time compared with the Gravel Edition. The Archives also said that 80 percent of the documents in Part V.B were omitted in the Gravel Edition. The printed versions of 1971 were "incomplete and had many quality issues" (National Archives page).

What this case shows

1. The country was fighting a war it could not read about. The study was commissioned by the Defense Secretary and kept secret. The public's information about the war's origins came from officials' statements, and the study, per secondary sources, showed gaps between those statements and private views. Voters cannot weigh a war if the record that would let them is classified.
2. The press, not an oversight agency, put the record in front of voters. The disclosure came from a defector inside the project, not from Congress or the courts. The Court's decision let the publication continue. Stewart wrote about "an informed and critical public opinion"; Black wrote of the free press's "duty" regarding government.
3. The decision limited prior restraint, not accountability for the leaker. White and Stewart both noted the Government could still prosecute. The Court said only that a court order to stop publication needed a stronger showing than the Government made. That draws a line between the public's right to read and the leaker's legal risk. We do not think the file should blur the two.
4. Even after the ruling, the public did not get the whole study for 40 years. The Gravel Edition left out most of one part and the House Armed Services copy was redacted. Full release came June 13, 2011.
5. The case against the leaker fell apart because of White House conduct, not the leak's merits. The break-in, the undisclosed wiretaps and the contact with the judge came to light in April and May 1973, months when the Senate Watergate Committee was already at work. The government's own methods ended a prosecution that a court was prepared to try. That ties accountability for the executive to what a trial can reveal.
6. The claim of grave harm was tested and not proven. The government's lead lawyer at the Court later said he had seen no such threat. That does not prove no harm occurred. It shows why a blanket "national security" claim is hard for the public to check.

The strongest objections, and our answers

1. Objection: Publication endangered troops and intelligence sources. The Government said so, and Justice White assumed substantial harm (NSArchive page). Three Justices dissented. Mitigation: no court found specific harm after full hearing, and Griswold later disclaimed it. But the Court did not rule the leak lawful; it ruled only on prior restraint. Both points stand.
2. Objection: Ellsberg broke the law and should be answerable. True on the facts in the record: he admitted giving the papers to the press (Wikipedia). The charge was never decided on the merits. Judge Byrne dismissed because of the government's conduct. We do not say Ellsberg was right; we say the trial was not completed.
3. Objection: The study was history, not a policy document, and the news was old. The study ended in May 1968 (Britannica). Nixon's own tape reaction was that it "all relates... to everything up until we came in" (NSArchive tape commentary). That is consistent with a limited effect on the Nixon administration and a larger effect on views of earlier ones. We do not claim it changed the course of the war.
4. Objection: Claims that Presidents "misled" the public are interpretation. Agreed. We cite them to History.com and Wikipedia and mark them as secondary. Our readers should check the Gulf of Tonkin volumes at the National Archives.
5. Objection: The Court acted too fast. Burger, Harlan and Blackmun said exactly that. Verdict notes the case "rocketed to the Supreme Court in less than two weeks." Mitigation: the delay was itself a cost; the newspapers were under a restraint for about two weeks.
6. Objection: The Plumbers link shows the leak caused the Watergate break-in. Not supported by what we read. The sources show a sequence: leak, leak-hunting unit, Fielding burglary, later arrests of some of the same men. We do not claim a single cause.
7. Objection: Gravel shows Congress used the leak for its own ends. Gravel v. United States held that the Speech or Debate Clause protects a senator's aide for legislative acts, but not for private publication with Beacon Press. The Court did not say whether reading the papers was wise.

Open questions: what would change our minds

• The study's content. We did not read the volumes. Claims about Presidents' statements come from History.com and Wikipedia. Check Part IV and the Gulf of Tonkin sections at the National Archives (PDF links on its Pentagon Papers page).
• Date of the lower-court orders. June 15 (TRO), June 18 or 19 (lifted or denied) and June 22 (Second Circuit) are from three secondary sources that differ. Read the district and appeals opinions.
• Indictment dates and counts. June 28, 1971 and Dec. 29, 1971 (15 counts) come from one LSU-hosted chronology. Wikipedia gives a different framing. Read the indictment or the Byrne order.
• Byrne and Ehrlichman. The Wikipedia page says Byrne met Ehrlichman twice and was offered the FBI directorship. The LSU chronology did not mention it. We have no primary source.
• Ellsberg's motives and 2021 to 2023 claims. Not used on this page.
• Griswold op-ed. We read the quote through the National Security Archive. The original op-ed would confirm the exact wording and context.
• Harm. Whether any published item harmed any person is not established by what we read. Government declassification reviews of the volumes might say.
• Pulitzer. The Prize citation reads "For the publication of the Pentagon Papers" (1972 Public Service, The New York Times). That is verified; we do not rely on it for any other claim.
• If a primary document showed concrete, documented harm from publication, Argument 6 would change.
