Yes sir:
The Liquid Sprayed on Ilhan Omar Has Been Identified
Hazmat crews have now confirmed the substance that was sprayed on Democrat Rep. Ilhan Omar (MN-5) during a town hall event Tuesday evening—and you might have some of it in your cupboard right now.
Deputy Managing Editor for RedState, Susie Moore, initially reported on the incident, in which a man later identified as 55-year-old Anthony Kazmierczak stormed the podium and sprayed Omar with a foul-smelling liquid from a syringe.
"I don't know how the incident involving Ilhan Omar on Tuesday evening will ultimately shake out, but no matter how you slice it, what happened was dumb," Moore wrote. "Don't be dumb."
Well, things have seemingly gotten dumber.
Officials have now confirmed the substance used was apple cider vinegar, according to reports — a non-toxic but notoriously pungent household item.
