A long time ago I read that Trump never uses email, on the advise of his lawyers. (True? I don’t know.) If so, I’ll bet that frustrated the evildoers who were trying to gather dirt.
He’s stated so publicly himself, whether it was during a press conference or a rally I can’t recall, but remember thinking it was an odd thing to say. In hindsight it might’ve been preemptive in case anyone were to try to entrap him on the basis of a fake email? Just guessing but it did feel as if saying that was directed at something in particular.
No lawyer uses email or computers other than jurisdiction issued software for filings with the courts. Knowing such gives us a lessons best learned glimpse.
