MINNEAPOLIS (AP) — A man who sprayed vinegar at Democratic U.S. Rep. Ilhan Omar at a town hall meeting in Minneapolis pleaded guilty to assault Thursday in federal court after reaching a deal with prosecutors.
Anthony Kazmierczak, 55, is awaiting sentencing.
Kazmierczak, dressed in bright orange jail clothing, gave only a fragmentary explanation Thursday of the Jan. 27 assault, which came as the city was already on edge after the fatal shootings of two people by federal agents during a White House crackdown that brought thousands of immigration officers to Minnesota.
After being asked what he remembered of the assault, he told U.S. District Judge Joan N. Ericksen: “It’s fuzzy.”
Kazmierczak, who was in the audience during Omar’s January town hall, leaped up when the representative called for the ouster of then-Homeland Security Secretary Kristi Noem. He sprayed liquid from a syringe as court documents say he shouted that Noem would not resign and that Omar was “splitting Minnesota apart.”
Security officers tackled Kazmierczak, who told them the liquid was vinegar.
“I didn’t want anybody to think she was in danger,” he said Thursday.
Omar, who was not injured, continued with the town hall after the arrest.
Authorities later determined he’d sprayed her with a mixture of water and apple cider vinegar. He was charged with assaulting a U.S. officer.
Court documents say Kazmierczak, a critic of Omar who has made online posts supportive of President Donald Trump, told a close associate several years ago that “somebody should kill” her.
Omar, a refugee from Somalia, has long been a target of Trump’s anti-immigrant rhetoric. After she was elected seven years ago, Trump said she should “go back” to her home country. He has described her as “garbage” and said she should be investigated.
Trump has also accused Omar of staging the attack, telling ABC News, “She probably had herself sprayed, knowing her.”
On Thursday, Kazmierczak told Erickson that he was being treated for Parkinson’s disease, and that he’d been diagnosed with ADHD or attention-deficit/hyperactivity disorder, and a form of post-traumatic stress.
After his arrest, his then-attorney said that he did not have access to the medications he needed for Parkinson’s and other serious conditions.
Minnesota court records show that Kazmierczak, who was convicted of felony auto theft in 1989, has been arrested multiple times for driving under the influence and has had numerous traffic citations. There are also indications he has had significant financial problems, including two bankruptcy filings.
In social media posts, Kazmierczak had criticized former President Joe Biden and referred to Democrats as “angry and liars.” Trump wants the U.S. to be “stronger and more prosperous,” he wrote.
Threats against members of Congress have increased in recent years, peaking in 2021 following the Jan. 6 attack on the U.S. Capitol by a mob of Trump supporters before dipping slightly, only to climb again, according to the most recent figures from the U.S. Capitol Police.
