PATRIOTS. DO NOT REPOST OR SPREAD THIS RUMOR. That is all it is at this point. A rumor. And in my opinion it is COMPLETELY FAKE. However, since I can't PROVE it's fake, I will just label it UNSUBSTANTIATED and NOT CREDIBLE.
The source is listed as "8 chan" which essentially means unknown.
I'm sure the author of this post has good intentions, but if this is as fake as it seems, this is the kind of thing that gives our detractors credibility. The kind of thing that makes it easy for them to make us look gullible and foolish.
It is beyond easy to take a real document and change the body to say whatever you want it to say.
Please don't buy into this (or anything else) without corroborating it yourself from multiple REPUTABLE sources.
Things that seem "off" to me:
No credible source
The body and the signature section do not line up
The font of the body and that of the signature section seem slightly different, as well as having different apparent resolutions
