He was trying to waste time the whole hearing. His "qualifiers" were mostly irrelevant. He would answer Harris' questions and she was ready to move on and he'd bring up some other unrelated bullshit to draw it out.
She asked about the specific DOJ policy he was citing for not answering questions. He started to go on a tangent about how other cabinet officials testified. She interrupted and again asked about the specific policy and whether it was in writing. He said he thought so. She asked if he had not reviewed it before testifying. He started to tell her the principle the policy was based on. She interrupted and said she wasn't interested in the principle. He clammed up and refused to answer, people intervened, he finally went on and on about the principle and her time was up.
It was clear that she was basically wanting him to cite the exact policy so she could get a copy of it and it was equally clear that he was trying not to give that to her.
The Trumpist line on yesterday's hearing was basically that Sessions's answers were brilliant, his memory perfect, his wit sharp and all concerns about the Russian ties are completely and totally put to rest. If you watched and don't recall any of that, and instead recall a stammering, nervous man who inexplicably refused to answer many questions and really only did well when being propped up by a friendly Republican senator. Well..Fake News!
Truth is no longer even an issue. Trump is perfect, no Russian meddling, greatest President ever. There is no lie too big. If the Great Wall of Mexico is never built, which of course it won't be, in a couple of years Trump will simply say it was built, and his supporters will say the Wall exists, and it's the greatest wall. And you can show them pictures of the Mexican border where there is no wall, and they'll say. Well...Fake News!
This Administration, one based on authority, don't need formal judgments of innocence. They don't even need a majority to support them. They just need a majority to not care enough to stop them.
