Man arrested in the attack on Minnesota Rep. Ilhan Omar is a convicted felon who has made pro-Trump posts

"When he was taken away, I could hear him actually say she's pitting us against each other"

The man who sprayed an unknown substance on Democratic U.S. Rep. Ilhan Omar at a town hall in Minneapolis is a convicted felon who has made online posts supportive of President Donald Trump.

Anthony Kazmierczak, 55, was convicted of felony auto theft in 1989, has been arrested multiple times for driving under the influence, and has had numerous traffic citations, Minnesota court records show. There are also indications he has had significant financial problems, including two bankruptcy filings.

Police say Kazmierczak used a syringe to spray an unknown liquid at Omar during Tuesday's event after she called for the abolishment of U.S. Immigration and Customs Enforcement and the firing or impeachment of Homeland Security Secretary Kristi Noem following the fatal shootings of Renee Good and Alex Pretti by immigration enforcement officers. Officers immediately tackled and arrested Kazmierczak, who was jailed on a preliminary third-degree assault charge, police spokesperson Trevor Folke said.

Photos of the syringe, which fell when he was tackled, showed what appeared to be a light-brown liquid inside. Authorities haven’t yet publicly identified the liquid, although there is at least one report from Liz Collin of Alpha News claiming the substance is apple cider vinegar.

After the attack, there was a strong, vinegarlike smell in the room, according to an Associated Press journalist who was there. Forensic scientists were called in, but none of the roughly 100 people who were there had a noticeable physical reaction to the substance.

Omar continued speaking for about 25 minutes after Kazmierczak was ushered out, saying she wouldn't be intimidated. While leaving, she said she felt a little flustered but wasn’t hurt, and that she was going to be screened by a medical team.

She later posted on X: “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.”

There were several journalists there along with the Associated Press.

"When he was taken away, I could hear him actually say she's pitting us against each other," added the BBC's Ana Faguy who is in Minneapolis and attended the town hall. "She took a moment. The room took a moment to collect themselves, and then they continued on with what they came out there to do, which was to talk about what's going on in their community."

A person holding a syringe charged Omar's podium while she spoke to community members. Protests and demonstrations continue around Minneapolis in the aftermath of the killings of Alex Pretti and Renee Nicole Good by federal law enforcement.

A Trump supporter

Kazmierczak hadn't been formally charged or scheduled for an initial court appearance as of Wednesday morning. The Hennepin County Attorney’s Office has until Thursday to charge him but could seek an extension. A spokesperson for the prosecutor’s office didn't immediately return a call seeking further information.

It isn't clear if Kazmierczak has a lawyer who could speak on his behalf. The county's chief public defender, Michael Berger, said the case hasn't been assigned to his office.

In social media posts, Kazmierczak described himself as a former network engineer who lives in Minneapolis. Among other things, he made comments critical of former President Joe Biden and referred to Democrats as “angry and liars.”

“Trump wants the US is stronger and more prosperous,” Kazmierczak wrote. “Stop other countries from stealing from us. Bring back the fear that enemies back away from and gain respect that If anyone threatens ourselves or friends we will (expletive) them up.”

In another post, Kazmierczak asked, “When will descendants of slaves pay restitution to Union soldiers families for freeing them/dying for them, and not sending them back to Africa?”

Often at odds with the president

Omar, a progressive, has been a frequent target of Trump's barbs since she joined Congress in 2019.

That year, Trump urged Omar and three other freshmen congresswomen of color known as “the squad” to “ go back ” to their countries if they wanted to criticize the U.S. Omar was the only one of the four born outside of the U.S., having immigrated to the country as a child when her family fled violence in Somalia.

Trump stepped up his criticism of Omar in recent months as he turned his focus on the Minneapolis-St. Paul area, which is home to about 84,000 people of Somali descent — nearly a third of the Somalis living in the U.S. During a Cabinet meeting in December, he referred to her as “garbage." And he has linked the Twin Cities immigration crackdown to a series of fraud cases involving government programs in which most of the defendants have roots in the East African country.

The White House did not respond to a Tuesday message seeking comment. But, when asked about the attack Tuesday night, he told ABC News that he hadn't watched the footage and accused her of staging the attack. “She probably had herself sprayed, knowing her,” Trump said.

Earlier Tuesday, the president criticized Omar as he spoke to a crowd in Iowa, saying his administration would only let in immigrants who “can show that they love our country.”

“They have to be proud, not like Ilhan Omar,” he said, drawing loud boos at the mention of her name.

He added: “She comes from a country that’s a disaster. So probably, it’s considered, I think — it’s not even a country.”

Lawmakers face rising threats

The attack came days after a man was arrested in Utah for allegedly punching U.S. Rep. Maxwell Frost, a Democrat from Florida, in the face during the Sundance Film Festival and saying Trump was going to deport him.

Threats against members of Congress have increased in recent years, peaking in 2021 following the Jan. 6 attack on the U.S. Capitol before dipping slightly only to climb again, according to the most recent figures from the U.S. Capitol Police.

Following Tuesday's attack on Omar, U.S. Capitol Police said in a statement that the agency was “working with our federal partners to see this man faces the most serious charges possible to deter this kind of violence in our society.”

Lawmakers have discussed the impact of the threatening political climate on their ability to hold town halls and public events, with some even citing it in their decisions not to seek reelection.
