Watching the original ad, and how it's impossible to even see the text in question at regular speed, makes me think it's more likely than not that the ad was created by a non Trump supporter who knew the Reich text was there already, hoping that someone with a big name in the Trumo space would eventually share it....in this case Trump himself....and voila you have another instant viral hoax.
Either way, this is again why no sane person believes ANYTHING reported by the "reliable" media when it's about Trump.
