I'm confused. I see something that looks like an email referring to the aforementioned email from Sari Koshetz.

I do not however see an email that looks like anything from Sari Koshetz with or without redaction.

EDIT: I agree with the user "martey" below, though, that this wouldn't necessarily be evidence of anything. It's way too easy to fake this kind of thing. The FOIA request for the email is the way to go. It'll probably find itself conveniently deleted or something, though.
