The only principle I see evidence of is resist President Trump at every turn. Jeff Sessions recusing himself almost immediately made him less valuable to POTUS. This termination is being characterized as a constitutional crisis by some in the hyperbolic camp, who extrapolate this into Trump to shutting down the Mueller investigation. President Trump didn't even fire Rosenstein when he was baited to by media.living sounds said:It might look that way, but it is about principles more than the people. Sessions won't ever be the darling of the left though, he has been and is being critized constantly for all the bad policies he advanced as well as for his underlying extremist views.
After two years in office he appears to be getting (only slightly) better at the swamp politics, but not being political was his previous charm.

PS: Speaking of banana republics, Chevron oil company is thinking about finally pulling out of Venezuela, after something like a century there. They made billions of dollars and out lived Chavez, but under Maduro they are no longer making enough profit to justify continuing. If they pull out, Maduro will lose his primary source of dollars and the economy will likely collapse (even further if possible), unless bailed out by China and/or Russia. Both of those countries have their own economic weakness on top of a falling oil price at the moment, but might invest if only to destabilize the Americas.
