She is making herself ridiculous and absurd.
She is an increasingly ridiculous person. Yesterday she informed the press that there were no Americans stranded in Afghanistan.
Her entire performance brought to mind a clip from an old movie called The Rocketeer. In The Rocketeer, a slow motion disaster was unfolding at an air show but the announcer kept reassuring everyone that what they were seeing was "all part of the show". I take Ms. Psaki's remarks to be along similar lines.
