Well - no he didn't. He invited a foreign power to find something. Any assault or other intention attributed is purely in your mind. It is wishful thinking too as last we heard the server was permanently off line. However, there is already a presumption in the republican camp that the server was already accessed years ago so it is more likely he was suggesting they search through whatever documents they already have.
Either way, anything outside of looking for or finding something is all something the viewer has to read into the statement. I'm certain Russia might take it differently - perhaps even as a joke. It depends on what they read into it.
