Not sure which posts you’ve read, or how much info you’re looking for. All I know is John Podesta allegedly sent out at least three emails with this picture of himself. https://pbs.twimg.com/media/Cwa_0NFUAAAjqlE.jpg:large . I read somewhere (don’t remember where) that those emails were leaked by Wikileaks, though I haven’t seen them myself. This picture was posted on twitter, https://mobile.twitter.com/WDFx2EU7/status/794533297279811584 . This is the earliest posting of the photo that I know of.
That’s all I know, other than speculation as to the meaning of it.
Thanks.
