I think this is theatre - POTUS poses as if he's disappointed with Sessions for strategic reasons. This fake hostility moves the left and the MSM over to Session's side to support him against Trump. It emphasizes Sessions' impartiality.
I’ve learned certain things over the years. One of them is how to read faces. That photo is simply awesome.
Nah, Donald Trump is sincere. He’s not using Sessions that way. Sessions is not that smart. There are prosecutors that can run rings around Sessions and that POTUS would love to have in the DOJ driver’s seat.
