@layman,
Another thing that Rosenstein said that's worth noting: Trump said he believed that Mueller would be exceeding the scope of his mandate if he undertook to investigate things not related to the russian investigation.
Trump caught hell for that from all the cheese-eaters, of course.
But Rosenstein confirms this. He says that Mueller would have to leave any such matter to the Dept. of Justice to deal with, and not undertake to do it himself. Rosenstein said Mueller would need to get an "extension" of the order to go beyond that.
He also said that Mueller understands that he is prohibited from embarking upon a "fishing expedition."
Nice try, cheese-eaters.
