If Trump is guilty then you miss the scope of the thing. If he starts talking to too many people, word would leak out. And, again, if he is actually guilty, he couldn't know how many people have access to the information or back-ups. This kind of dirty politicking only works because no one on that team believes it will ever get out, or if it does, that it will be much more than one more huff and puff before dying away in the endless news cycle.
