What could you expect from someone who only showed up for work to collect his paycheck. I doubt Mueller had much input into the investigation, and wrote little or none of the report. He was just the figure-head, and left the legwork to his minions. I think the guy is totally inept. It’s the same way Comey ran the FBI...turned it over to the inmates to run the asylum, and was Director in name only. Comey learned that technique from someone...probably from his buddy Mueller. And Wray seems to be following in their footsteps.
ding ding ding we have a winner, Mueller was a figurehead nothing more to give cover.
