I don't read a lot into the Sessions relationship just because we don't know what it actually is. We have what the MSM reports, but not the actual relationship. What was discussed prior to the appointment and what we have after may be completely different than what we think. Has to play out some more. What I do like is Trump isn't worried about what is being reported.
We see Trump himself publicly proclaiming his disappointment in Sessions. We see him driving that point home with repeated tweets. We see him demonstrating phenomenal public disloyalty and disrespect toward one of his earliest and most loyal supporters. We see Trump oblivious to the support Members of Congress are showing for Sessions and the new strong criticism from these same people against Trump. We see normally supportive media outlets like Breitbart taking an anti-Trump stance on this matter.
Trump needs friends to get things done in Washington and he seems to be doing everything he can to convince people that Trump is no friend of theirs. It's Trump first and, if it suits Trump, under the bus with his supporters.
Suspend judgement if you wish. Consider some behind-the scenes relationship if you wish. I'm going with what is publicly obvious.
For understanding Trump relationships,
this piece may be helpful. Trump creates and thrives on chaos. What's going on with Sessions is not new for Trump. It's just Trump being Trump. However, he is president now and Trump's chaotic ways will not work forever. Trump being Trump is what will get him impeached.
He took a big step in that direction by demonstrating disloyalty to loyalist Sessions and thereby showing Members of Congress that for Trump loyalty is not a two-way street. He'll need loyal friends when impeachment proceedings start and he will not have them.
Gentleman Pence waits in the wings.
