This image has not been altered by me in any way. On a computer monitor (as opposed to a phone screen) it appears more visibly.
I tried to link the source of this image, but the DKos content management system said it is a site it doesn’t allow to be sourced (sunlight foundation). It is from Nov. 2018. I found it while searching wikimedia commons.
Medical friends of mine have said it could well be an ostomy bag of some sort. This is not to shame people with such medical needs. But as he promotes himself as the “healthiest president ever,” it is worthwhile to question.
At the risk of running afoul of DKos rules, here is a bitly of the source photo, if it works: bit.ly/…
Once again, I made no edits whatsoever to the photo, only zoomed in on it on my computer monitor, and took a photo of it with my phone.
