“At my confirmation hearing in March 2017, a Republican senator asked me to make a commitment,” he recalled. “He said: “You’re going to be in charge of this [Russia] investigation. I want you to look me in the eye and tell me that you’ll do it right, that you’ll take it to its conclusion and you’ll report [your results] to the American people.
“I did pledge to do it right and take it to the appropriate conclusion. I did not promise to report all results to the public, because grand jury investigations are ex parte proceedings. It is not our job to render conclusive factual findings. We just decide whether it is appropriate to file criminal charges.”
Rosenstein is leaving his post in two months. He had some fun with his speech and answered the question that so many on social media were asking after watching him standing stoically behind Attorney General William Barr during the lead-up to the Mueller report release.
“Last week, the big topic of discussion was, ‘What were you thinking when you stood behind Bill Barr at that press conference, with a deadpan expression?’ The answer is: I was thinking, “My job is to stand here with a deadpan expression.’”
