“Trump fired Comey. Can’t he fire this chump too? “
The real question is, “Is that the wisest thing to do at any particular moment in time?” When Trump fired Comey, he got the Mueller investigation THAT WEEK. If he fires Rosenweasel, what will be the push-back? How will it affect the election? These are all of the things that Trump has to consider - IOW, it isn’t just about scratching an itch and being satisfied about how good it feels to do that.
Thanks for the good points.
