Can a Podcast Guest Be Sued for What They Say, or Only the Host?

Who Can Be Sued for a Defamatory Statement on a Podcast?

Anyone who takes part in publishing it, starting with the speaker. US defamation is mainly state law; a claim generally needs a false statement presented as fact, publication to a third party, the required level of fault and reputational harm (Cornell LII, Wex). None of those elements turns on whether the speaker is the host or a guest.

Repeating a claim does not make it safe. Law professor Eugene Volokh describes the long-standing “republication rule,” under which a person who repeats a false allegation is “potentially liable for defamation” even when they attribute it to someone else, citing Restatement (Second) of Torts §578 (Volokh Conspiracy). Volokh notes exceptions, such as the fair report privilege.

Plaintiffs can sue the people associated with a statement and its publisher together. In New York Times Co. v. Sullivan, 376 U.S. 254 (1964), a Montgomery city commissioner sued the Times and four Alabama clergymen whose names appeared in a full-page advertisement. A jury awarded him $500,000 “against all the petitioners” before the Supreme Court reversed (Sullivan, Cornell LII).

What Does a Plaintiff Have to Prove in the US?

It depends on who the plaintiff is. Sullivan bars a public official from recovering for a defamatory falsehood about official conduct “unless he proves that the statement was made with ‘actual malice’—that is, with knowledge that it was false or with reckless disregard of whether it was false or not” (Sullivan). The Court later extended it to public figures (Wex).

Private people face a lower bar. In Gertz v. Robert Welch, Inc., 418 U.S. 323 (1974), the Court held that “so long as they do not impose liability without fault, the States may define for themselves the appropriate standard of liability” for a publisher or broadcaster of defamatory falsehood about a private individual. It limited presumed and punitive damages in those cases (Gertz, Cornell LII).

Opinion labels are not a reliable defense: Wex says “merely characterizing a statement as an ‘opinion’ does not automatically protect it,” citing Milkovich v. Lorain Journal Co., 497 U.S. 1 (1990). Fault is assessed for each defendant, so a guest and a host can end up in different positions over one episode. This is not legal advice.

Does Section 230 Protect the Guest or the Host?

It does not protect the guest from their own words. Section 230(c)(1) says: “No provider or user of an interactive computer service shall be treated as the publisher or speaker of any information provided by another information content provider.” Section 230(f)(3) defines an information content provider as “any person or entity that is responsible, in whole or in part, for the creation or development of information provided through the Internet or any other interactive computer service” (47 U.S.C. §230).

A guest who says something on air created that information, so the guest is its information content provider. The protection covers information provided by another provider; it gives the speaker nothing for their own statements.

The host and producer are a harder question. Whether a podcast that records, edits and publishes a guest’s words is a “provider or user of an interactive computer service,” and whether editing makes it responsible “in part” for those words, the statute text does not settle. We did not find a court decision applying Section 230 to a producer’s own episode, so we make no claim either way. In a different context, the FTC argues Section 230 does not cover content a platform “materially contributed” to developing; see platform liability for scam ads. This is not legal advice.

What Happened to the Guest in Kielburger v. Canadaland?

Theresa Kielburger, mother of the WE Charity co-founders, sued Canadaland Inc., founder Jesse Brown, staff and Isabel Vincent over the August 2021 episode of The White Saviors. The judge wrote that “Brown was host and Vincent was a guest”; Vincent, a journalist outside the Canadaland team, had written the 1996 Saturday Night article the episode revisited (Kielburger v. Canadaland Inc., 2024 ONSC 2622, reasons as reproduced by a WE supporters’ site).

Why Did the Guest Get Out When the Host Did Not?

Because the judge looked at each speaker’s own words. Ontario’s anti-SLAPP law requires dismissal of a claim arising from expression on a matter of public interest, unless the plaintiff shows grounds to believe the claim “has substantial merit,” the defendant “has no valid defence,” and the harm outweighs the public interest in the expression (Courts of Justice Act, s. 137.1).

The judge found that Brown’s repetition conveyed the 1996 claim about donations as true. He wrote: “It is far less clear that Vincent participated in these statements. Her words were carefully chosen and she did not comment on or summarize or repeat the Money Passage the way Brown did.” A separate remark of Vincent’s could be read as defamatory, but he found it “far closer to opinion than fact,” giving her “the prospect of a valid defence of fair comment.” He also found “no reason to believe that Brown and Canadaland have any valid defence” (2024 ONSC 2622).

The ruling does not say guests are safe. Addressing the plaintiff’s joint-liability argument, the judge quoted the Supreme Court of Canada: “If one person writes a libel, another repeats it, and a third approves what is written, they all have made the defamatory libel.” Vincent escaped on her own wording, after being named as a defendant.

What Did the Case Cost Each Side?

In the costs endorsement, the judge wrote that Vincent’s “careful approach saved her from any liability, but it did not save her from being named as a co-Defendant with Canadaland and having to defend herself” (2024 ONSC 3856). Ontario’s law presumes full costs for a defendant who wins the motion; we did not check whether any US state does the same.

The chart shows that the costs the plaintiff was ordered to pay the guest, $90,000, came close to the $110,000 the host’s company was ordered to pay, before any settlement.

The settlement release, distributed by WE Charity, adds a $775,000 payment to the $110,000 costs, for $885,000 in total, and requires that an audio retraction “be inserted into the original podcast episode, replacing existing versions on all platforms” (Newswire; Podnews). None of these documents names a currency, and we did not check whether the audio was replaced.

What Can a Guest Do Before Recording?

The steps below are our recommendation, not a court rule.

What This Means for Anyone Buying a Placement

A paid guest spot is advertising and should be disclosed. Paying for it does not move responsibility for what you say onto the host. Our recommendation, not a rule: brief the spokesperson on which claims they can document, avoid repeating allegations about competitors or critics, and get the show’s correction process in writing. No booking can guarantee that an episode stays unchanged. If an episode about your company goes wrong, see how to respond to a negative news article.

Methodology and Limitations

Four limits apply. First, the US law here is general; we read no state’s defamation or anti-SLAPP statute, and California’s official code site blocked access. We also could not read the Restatement itself. Second, CanLII blocked access, so we read the 2024 ONSC 2622 reasons as reproduced on a site run by WE Charity supporters, and the 2024 ONSC 3856 costs endorsement as a CanLII copy hosted by Canadian Lawyer. Third, the settlement terms come from the plaintiff side’s release. Fourth, we did not find a US decision on Section 230 and a producer’s own episode, and the Canadian rulings came at the anti-SLAPP stage; no court decided liability at trial. This is not legal advice.

Conclusion

A guest can be sued, and has no Section 230 argument about their own words. The Canadaland case shows both sides. The guest who chose her words carefully left the case early, and the host who repeated a disproved claim paid $885,000 in damages and costs, according to the plaintiff side’s release. Anyone booked on a show should treat every factual claim about a named person as their own, because the cases treat it that way.
