The Washington Post has just broken the story that Deputy Attorney General Rod Rosenstein, for fear of losing his job, assured President Trump that Mr. Rosenstein was on the president's team, that he would "land the plane" (ie. the Mueller investigation) and that the president was not the target of the probe. That disclosure explains why Mr. Rosenstein abetted Attorney General William Barr in "exonerating" Mr. Trump despite overwhelming evidence of obstruction and why he is now attacking the media and the Obama administration.
It is now imperative that Congress find out whether and how often Mr. Rosenstein met with Special Counsel Mueller, what was discussed and whether Rosenstein gave him any directions or imposed any limitations on the investigation. It is high time we heard from Mr. Mueller himself.
