“Watching Mueller testify in 2019 about the “Russia-gate investigation,” I realized, like Joe Biden, he’s a corrupt, demented old patsy who probably can’t think beyond what pudding he will have after his nap.”
That was my impression as well. Andrew Weissmann was technically #2 but he had assembled the Mueller team before Mueller was asked to lead it. Weissmann had to be the actual leader.
I thought that Mueller was faking it when he testified. He is a trained liar.
