Anthony James Kazmierczak has pleaded guilty in federal court to assault charges for spraying vinegar at Democratic U.S. Rep. Ilhan Omar during a town hall meeting in Minneapolis.

The incident occurred in late January at a public town hall event where Omar was meeting with constituents. Kazmierczak sprayed vinegar at the congresswoman during the gathering, leading to federal assault charges.

Kazmierczak reached a plea deal with federal prosecutors before entering his guilty plea in court. The specific terms of the plea agreement were not immediately disclosed.

The attack took place during a period of heightened immigration enforcement activities in Minnesota. Omar, who represents Minnesota's 5th congressional district, regularly holds town hall meetings to engage with constituents on various policy issues.

Federal authorities handled the prosecution of the case, as attacks on members of Congress fall under federal jurisdiction. The congresswoman was not seriously injured in the incident.
