Again, this smacks of a disinfo campaign that major Twitter influencers are latching onto. Random ppl from FL to KA to NH getting weird letters like this? There's a strong likelihood it's just far-right ppl printing and sending letters to ppl in their own neighborhoods. https://twitter.com/RealJamesWoods/status/1318816744065040384

They've done it before—it's the same type of thing. All the same features. https://twitter.com/areidross/status/1277417695357501440?s=20

The first time I saw this letter was a couple of days ago circulating far-right groups. I think this is the earliest appearance I've been able to track down—on Sunday... coming from a NC blog that talks about a Massachusetts letter. No source provided. https://ncrenegade.com/editorial/remember-it-is-your-fault-that-we-attacked/

Hmmm! A user of this far-right message board who claims to be from Southern New Hampshire posted the NC article shortly after publication... Could it be that the same NH user printed off a version of the same piece and dropped it off at homes in southern NH towns 8 miles apart?
