The attack on Rep. Ilhan Omar, D-Minn., at a Minneapolis town hall Tuesday was both reprehensible and inevitable. Police believe the syringe contained apple cider vinegar, CNN reported, citing a law enforcement source familiar with the investigation. You don’t have to agree with Omar’s politics (and we often don’t) to find the assault repugnant. The urge to brand those of opposing views as evil and out to destroy the country are too great to resist, sadly. Rep. Maxine Waters, D-Calif. took heat in 2018 for giving a thumbs-up to heckling members of the Trump administration in public.
