into an all-out assault by the president on one end of pennsylvania avenue and the republican congress on the other end of pennsylvania avenue against the mueller investigation, against an independent justice department, and against the rule of law. and it is a dangerous time. this to me feels like the most dangerous time for the mueller investigation really since he was appointed in may of last year. >> why? why does it? >> because you see this confluence of the president wanting to fire rod rosenstein, presumably to replace him with someone who maybe wouldn't fire bob mueller, but wouldn't approve new lines of investigative inquiry, wouldn't approve new indictments, maybe would curtail his budget, would kind of sit on his head and slow-walk the investigation and shut it down. and on the other end of pennsylvania you have house republicans who not only are not standing up to the president, but are enabling the president and helping him try to shut this down. >> rosalind helderman and matt miller, thanks for your time. coming up, how upset was the president on fiing robert mueller?
