“I believe that many, including many in the press, have done the country a disservice by creating the impression that when he gets done, Mueller is going to write this scathing, lengthy report detailing what an asshole the president is, even if he’s not a criminal,” says Paul Rosenzweig, a senior fellow at the R Street Institute think tank who was a senior counsel on the Whitewater investigation. “If my thesis about Mueller is right, then that’s just not happening.”…

…“Prosecutors who decline cases just close,” Rosenzweig said. “They might write a memo to the file about why they didn’t prosecute. With very rare exceptions, which by the way get condemned—see James Comey—prosecutors who decide not to do anything put everything in a box and send it to archives.”
