Jen Psaki seems like the kind of asshole you knew back in school who never actually read the books but gave her oral reports in front of class anyway. Despite it being completely obvious that she was full of shit, her narcissism emboldened her enough to never break "character". If anyone dared to challenge her instead of acknowledging her lack of preparation she'd gaslight them by doubling down, for everyone to see. Fooling absolutely no one, she pretended otherwise at all times. Someone to avoid, for sure.
