Deputy Attorney General Rod J. Rosenstein appointed special counsel Robert S. Mueller III nearly two years ago “to ensure a full and thorough investigation of the Russian government’s efforts to interfere in the 2016 presidential election,” as he put it then. Mueller’s report, submitted to the Justice Department on Friday, is titled: “Report on the Investigation into Russian Interference in the 2016 Presidential Election.”
This was supposed to be the last word on Russian interference, a definitive investigation that would show the United States and the world, in detail, how it happened — and, as a subsidiary question, whether Trump campaign officials were involved.
