The press had been running DNC-provided speculation that "Russia did it" (respecting the DNC emails) as hard news for a couple days. They were primed to see Russia from wherever they were. Oh, and to see a Trump connection to the DNC email leak, too.
So Trump says maybe the 30,000 (private, supposedly not work related at all) e-mails deleted by Hillary can be found by the Russians.
Hillary's camp cries out, "He's calling for espionage of state secrets!"
The best spin Hillary can put on this, once you see the pieces, is that Hillary and the press are stupid beyond your wildest imagination.
At any rate, it was a well-timed tweak. The press was seeing Russians in every shadow, and he hit them directly where their overactive imaginations wanted to be hit.
He basically made them all admit they were lying when they said there was no classified intel in those emails. If that were true this wouldn’t have blown up!
