Any evidence he lied? Nah, what am I talking about. You believed Trump colluded with Russia for almost three years without a shred of evidence. Of course you wouldn't need evidence to believe Barr lied.
You need serious work on your condescension. You truly suck at it. It may be hard but trying to think like an adult might help you. Probably won't but you need all the help you can get so you should try something. Anything. At least bring it up to a college level. This high school mentality of yours is too low for me to go. If you wanna play you're going to have to put on your big boy panties. I'll acknowledge you if you grow up otherwise .. toodles.
“I, WILLIAM BARR, DO SOLEMNLY SWEAR THAT I WILL SUPPORT AND DEFEND THE CONSTITUTION OF THE UNITED STATES AGAINST ALL ENEMIES, FOREIGN AND DOMESTIC; THAT I WILL BEAR TRUE FAITH AND ALLEGIANCE TO THE SAME;; THAT I TAKE THIS OBLIGATION FREELY, WITHOUT ANY MENTAL RESERVATION OR PURPOSE OF EVASION; AND THAT I WILL WELL AND FAITHFULLY DISCHARGE THE DUTIES OF THE OFFICE ON WHICH I AM ABOUT TO ENTER. SO HELP ME GOD.”
