It might sound odd, but the firing of Rex Tillerson has changed my opinion on Sessions. Trump never publicly criticized Tillerson but fired him likely due to policy disagreements. Trump publicly criticizes and even insults Sessions and does nothing else?
I don't know if I trust Sessions, but I do trust Trump more than most other politicians. Still, he is capable of errors in judgment.
If something big is going to break it needs to break soon, since midterms are coming up. Too close to midterms and it'll look like a political stunt.
