I had seen the Psaki name several times,and had to click on this link to see who it is.
No surprise about what she says. She is the WH Press Creature,and part of her job is to act the fool to take attention away from the actual fool in the WH.
Of course,there IS the positility she actually believes the brain farts she issues. After all,she IS a Dim.
BTW,didn't they have someone else doing this just a short time ago?
