I think we can all agree that if the Secretary of the United States chose to use an unsecured computer to communicate classified information, then foreign powers will have that information.
Trump is essentially saying that Russia undoubtedly already has everything that server had. How could they not? How long was she using that server for? How many classified pieces of information did she send and receive through that server?
To assume that it was never touched by a foreign power is the height of arrogance. Or perhaps complacency, incompetence, or even apathy.
So he's not calling for active espionage. He said, "Hey, Russia, since you probably already have the 30k emails that Clinton deleted in order to avoid prosecution, wouldn't it be funny if they ended up in a newsroom in the US?"
In other words, he's asking russia to admit to espionage and attack Clinton at the same time.
Neither of which Russia will do openly, I'd guess, but it wouldn't surprise me if at some point during the campaign certain emails started leaking slowly to the press, and not necessarily from Russia.
I could be wrong about the "openly" part. I'm truly surprised at the open collusion between the DNC and the Clinton campaign boldly on display right at the beginning of the convention. It's truly mind boggling.
What a time to be alive.
