It’s the immediate recusal and abdication of all major responsibilities that brought this disaster about. Hindsight is 20/20, but it’s hard to figure out how Trump could have known that the biggest vetting question he needed to ask was re recusal. And anyway what would have stopped Sessions from lying? Had he been honest, he’d have told Trump proactively that he was planning to recuse. But Sessions wanted that job so he kept his plans a secret.
Absolutely, that job as AG was Session’s life long dream. So he kept his recusal hidden in his pocket. That way he gets the job, and does not ever get in cross-hairs of the democrats infesting DOJ.
POTUS has full constitutional authority to fire ANY ONE working in the executive branch. Sessions and Rosenstein should be fired before more damage occurs. Firing Mueller will have to wait until a federal court rules on his over-reach.
