Have any firsthand witnesses or staffers publicly claimed Donald Trump used adult diapers?

1. How the “diaper” story first circulated: rumor, meme and a single online narrator

The claim that Donald Trump wore adult diapers did not emerge from a hospital record or an on-duty staffer’s deposition in the articles provided, but from viral social-media content and partisan videos: reporting traces a notable early iteration to videos and posts promoted by anti‑Trump groups that framed incontinence as an insult or punch line, and at least one individual—reported by TheWrap—made allegations presented without corroboration and without clear firsthand witnessing of the specific act ^[1].

2. Journalists and outlets call the allegation unsubstantiated rather than corroborated

Mainstream coverage in the available sources treats the allegation as unproven: TheWrap explicitly described the claim as “so far unsubstantiated” and noted the originator did not offer direct evidence or documented firsthand observation of Trump wearing diapers, while a local TV feature said reporters investigated the rumor because it had gained traction on social platforms but did not present conclusive proof of diaper use ^{[1] [4]}.

3. Opinion and satire amplified the image rather than verified facts

Commentary and political advertising turned the rumor into satire and talking points: an opinion column in the Los Angeles Times discussed the “Diaper Don” meme and emphasized that the author had no personal knowledge of Trump’s bodily functions, framing the episode as part of modern campaign rhetoric and mockery rather than reportage of a factual medical condition ^[2]. The Lincoln Project, similarly, used diaper imagery in an ad to ridicule Trump’s courtroom appearances—an act of political theater that promoted the idea without offering firsthand testimony ^[3].

4. Supporters and opponents weaponized the claim in public events and merchandise

Rather than emerging from inside claims by staffers, diaper imagery spread through rallies and merchandise: reporting noted Trump supporters intentionally wore diapers and T‑shirts reading “Real Men Wear Diapers” as a provocation and a way to reclaim the taunt, while other groups sold “Trump Diapers” as parody merchandise in political ads—again, cultural mockery and political symbolism, not corroborated eyewitness staff testimony ^{[5] [3]}.

5. Why credible firsthand testimony is absent in the cited reporting

The corpus available emphasizes social‑media virality, partisan videos, opinion pieces, parody ads and local TV curiosity segments rather than medical records or sworn statements; TheWrap’s reporting specifically flags the claim as uncorroborated and notes the claimant’s lack of credited production credits to substantiate long claimed employment that might bolster access, underscoring the absence of verified staffer testimony in these sources ^[1].

6. Bottom line — what this set of reporting supports and what it does not

Based on the materials provided here, there is no documented, credible, on‑the‑record claim from a firsthand witness or recognized former staffer that Trump used adult diapers; the narrative in circulation is demonstrably a mixture of rumor, political ridicule and unverified allegation, with outlets repeatedly labeling it unsubstantiated rather than proven ^{[1] [2] [3]}. These sources do not prove the negative either—they do not, for example, cite hospital files or sworn staff affidavits—so the safest, evidence‑based statement drawn from this reporting is that public discourse has been driven by memes and partisan attacks, not by verified eyewitness accounts ^{[1] [4] [5]}.
