mueller, it's the second time we heard tonight that having been described as having a pretextural feelwhat's wrong with offering up a plainly stupid or thin transparent or obviously untrue justification for doing something? if the president has it in his power to fire anyone he wants to, why does it matter he would offer a plainly false reason for doing so? >> one is intent. that's one element of an obstruction case. and if it's pretextual, it focuses more on what his intent might have been. it reminds me of the firing of jim comey, which was that the president was disturbed by the way he treated hillary clinton. then it turned out that wasn't the reason at all. i don't think that, again, did much for his communicating successfully that he had any sort of, you know, genuinely law enforcement centered intent as opposed to a self-protective intent. >> and a self-protective intent, of course, is a big part of understanding what obstruction is versus lawful action. bob bauer, former white house council to president obama, thank you for joining us on short notice. >> a pleasure, thank you.
