With the reporting that three different people knew of the e-mail, and the person who sent the e-mail has been identified,it seems fairly believable that there is an e-mail,and that Donald Trump Jr. read it. Because he did have the meeting it seems obvious that he is guilty of conspiring with the Russians to commit cyber terrorism. It doesn’t matter if the information was helpful or not. What matters is that he knew why the meeting was scheduled, and he met with Russians.
AS CNN explained: this e-mail would be “completely and totally damning“!
