"A cause of action for intentional infliction of emotional distress exists when there is ‘(1) extreme and outrageous conduct by the defendant with the intention of causing, or reckless disregard of the probability of causing, emotional distress; (2) the plaintiff’s suffering severe or extreme emotional distress; and (3) actual and proximate causation of the emotional distress by the defendant’s outrageous conduct.’ A defendant’s conduct is ‘outrageous’ when it is so ‘extreme as to exceed all bounds of that usually tolerated in a civilized community.’ And the defendant’s conduct must be ‘intended to inflict injury or engaged in with the realization that injury will result.'"
Quoting somebody's actual words is in no way "outrageous" under that standard. People in civilized communities quote what other people say all the time. And even if the didn't, the first amendment strongly protects political speech, and quoting somebody else's political speech is pretty obviously part of that.
