Omar sprayed at town hall 

The backstory:

Kazmierczak was in the audience at Rep. Omar's town hall event at the Urban League Twin Cities headquarters in north Minneapolis back in January. Prosecutors say he rose from his seat, shouted at Omar, and rapidly approached her with a syringe, spraying her with a liquid later determined to be apple cider vinegar.

Video shows Kazmierczak being quickly tackled after the spraying and arrested. Police say he told officers that he squirted Omar with vinegar after being arrested.

Despite concerns from other town hall attendees, urging her to go get evaluated, Omar went on with the town hall after the attack.
