Man who sprayed Ilhan Omar with vinegar to plead guilty on federal charge

The Minneapolis man who sprayed Rep. Ilhan Omar, D-Minn., with vinegar during a January town hall is changing his plea to guilty on federal charges stemming from the incident.

Anthony James Kazmierczak’s assault on Omar occurred weeks after Renee Good was killed by an ICE agent, which heightened tensions between federal officials and Democratic state leaders to an all-time high. Democratic leadership called for federal agents to leave Minnesota.

In March, Kazmierczak pleaded not guilty to one federal count of assaulting a United States officer, but an April court filing from his attorney, John Fossum, stated that Kazmierczak will change his plea to guilty after they have “reached a settlement” with federal prosecutors. Kazmierczak’s change-of-plea hearing is scheduled for May 7.

The exact details of the settlement are unknown. Digital reached out to Kazmierczak’s lawyer for comment.

Video of the Jan. 27 town hall showed Kazmierczak rushing the stage as Omar spoke. She was calling for Department of Homeland Security Secretary Kristi Noem to step down and for ICE agents to leave Minnesota.

He pulled out a syringe filled with apple cider vinegar and water and attempted to douse the congresswoman with the liquid before an officer stepped in.

“She’s not resigning,” Kazmierczak said in the video, referring to then Department of Homeland Security Secretary Kristi Noem.

Kazmierczak also pointed his finger at Omar, screaming, “you’re splitting Minnesotans apart.”

Omar was not injured and continued her town hall after Kazmierczak was arrested.

“I’m ok. I’m a survivor so this small agitator isn’t going to intimidate me from doing my work. I don’t let bullies win. Grateful to my incredible constituents who rallied behind me. Minnesota strong,” Omar wrote in a post on X at the time.

Since the incident, Kazmierczak has been held in custody. A magistrate judge ruled that the “exceedingly serious and dangerous circumstances” of the assault allegations make it impossible to ensure that public safety is not at risk if Kazmierczak is released on bail.

During the investigation, an FBI agent interviewed an associate of Kazmierczak, who claimed that Kazmierczak once said that “somebody should kill” Omar.

“Assaultive behavior and acts of intimidation directed at officers and employees of the United States will not be tolerated,” said United States Attorney Daniel N. Rosen. “Persons who engage in this criminal conduct can expect a swift response from law enforcement and federal prosecutors
