No, he acted like someone being incredibly careful not to get tripped up on a trick question or answer anything beyond his “perview”. He strikes me as someone who quietly goes about his work and may loathe public speaking and media attention (unlike Trump). I think he did state that putting the report together involved delegating tasks. He was the boss so he didn’t do it all singlehandedly. I wouldn’t expect him to. Even if he didn’t write it, it’s reflective of the work he and his team did, and he still signed off on it and stands by it. And even if he did do it all, he can’t memorize word for word, page for page, what he wrote about who said what. So he was very careful not to make a misstatements based on leading questions. He made it pretty clear that Trump was not exonerated for obstruction of justice - he said it was “correct” that Trump ordered McGhan to falsify documents and that Trump had asked McGhan to fire Mueller himself - but that criminal charges can be brought against a sitting president according to DOJ protocol, which he abided - it was not in his mandate but he also doesn’t believe Trump is above the law - but addressing the obstruction behaviours. So it’s now congresses’ job to impeach Trump. And once he is out of office he can be arrested.
It was boring. I fell asleep only 1/2- 1 hr into it and am catching up on key details...which are all in the report that he kept redirecting the questioners to. Mueller confirmed under oath that what is in the report is correct. He wouldn’t throw away his whole career - the man has brought down mafia kingpins - to lie about Trump.
