Answer: The comic Noel Casler worked on Celebrity Apprentice for six seasons. Unlike his colleagues, Casler thwarted his nondisclosure agreement, enabling him to tell us what he witnessed over his time working on set in close proximity to Trump. The following quotes are taken from this interview clip and this article: "He's [Trump] incontinent from all the speed, all the Adderall he does, the cocaine that he has done for decades. All that stuff has a laxative effect on your bowels and his are uncontrollable." Casler said that Trump has been wearing 'diapers since probably the 90s'. Adding that they often had to stop the show in order for Trump to change his diaper, Casler said that Keith Schiller's job was to take Trump offset and wipe him down. "Our nickname for Keith was wet wipes." Casler added that Trump does it and he almost sits there unaware of it, and one time he saw Ivanka have to kind of go whisper in his ear and then Keith came and took him offstage. "Trump not cleaning himself when changing out Depends, it is because he wears a hard plastic girdle and he doesn't have the freedom of movement. It's why you see him turn his body from the waist so strangely when standing." "He would soil himself often after flying into a rage and cursing out the Script Dept because he couldn’t read a word. One time there was the word 'arbitrage' on a cue card and he freaked out and started screaming that the script department was setting him up then very loudly evacuated his bowels and you could smell it." Other celebrities have vouched for Casler's credibility, but his biggest credibility booster is that despite his violation of the NDA no lawsuits have followed. Considering past threats of hellfire litigation from Apprentice producers to NDA signers and Trump's love of suing people into poverty for any frivolous thing, that's pretty huge. I should also mention that Casler originally came out about this around 2019, but when the pandemic hit the story was mostly buried. This discourse was reignited by a recent tweet from former Republican Congressman Adam Kinzinger: I’m genuinely surprised how people close to Trump haven’t talked about the odor. It’s truly something to behold. Wear a mask if you can. Kinzinger later elaborated on the scent in an interview: It’s not good. The best way to describe it...take armpits, ketchup, a butt and makeup and put that all in a blender and bottle that as a cologne. That’s kind of that. I’ve been amazed that everybody is just kind of learning about this now. Here is a detailed 1 hr 20 min podcast that interviews Casler about these topics and more. And here's another one. Google 'noel casler trump' and you will find even more Casler interviews on YouTube. There are too many to post here. Enjoy! EDIT: In the linked interview Casler mentions Trump's appearance on WWF's Battle of the Billionaires in 2007, in which Trump tackles Vince McMahon outside the ring and you can see the outline of what appears to be a diaper. => Trump tackles McMahon at 0:55 In the same clip Casler mentions a couple times where he believes that Trump soiled himself on TV while in office, one of which was a press conference with Turkish President Erdogan. => Here's the cut down clip of the moment in question. To prove the audio isn't doctored I'm also linking the full press conference from CSPAN's view and the same conference from PBS's view Casler also mentions a press conference with Sen. Feinstein. => Here's the press conference with Feinstein next to Trump. The questionable moment is at 0:21. There are other questionable sounds throughout the video. I'll let you all be the judge
