I don’t think Trump was entirely sincere. I think it was so over the top complimentary that it will come across as sarcasm to Barr. Something along the lines of I know what you are doing and what you are all about.
Did you read Sundance’s comments? POTUS is on to the next hurdle. IF Barr IS a dirty cop (fixer) then he’ll get the boot soon enough. POTUS has to keep his eyes on the prize and win the election (and the House back) THEN he can FIRE the resistance.
4ight re: this maybe not being the moment to fire Barr. But he has been a corrupt Bush/CIA fixer for decades. Never should have been hired by Trump.
