Mueller obviously didn't agree. But Barr was well within his rights after a couple of years to shut that portion down and get mutual agreement under the circumstances from Mueller because he'd kick the snot out of Mueller if he whined about it. It is the AG's call. They agreed to disagree and end it.

For Russia, they didn't know all the answers. So what concrete steps would Mueller be taking to determine if he could get proof beyond reasonable doubt after nearly two years plus FBI investigation time? Basically fishing and trying to shake down people they're prosecuting - getting them to flip - something vague like that. So Barr would hit him on specifics of what was left. "You've had two years , Bob. What is left for you to examine?" Mueller's vague. Barr cuts his budget. Game over.

When Barr was nominated, Mueller had to see the writing in the wall. Barr is partisan. Mueller not so much so. When Whittaker didn't pan out, Trump got his man to shut it down.
