The man captured on video aggressively approaching Rep. Ilhan Omar with a syringe is being condemned by his own brother as a “piece of s–t” with a long-standing “hatred” for the Somali community. This revelation comes after the unsettling incident, which has left many appalled.

“I’m not surprised this happened,” shared the estranged brother of Anthony Kazmierczak, who chose to remain anonymous. Speaking to the Independent from his residence in North Carolina, he reflected on the alarming event that took place during a public meeting in Minneapolis.

“Not at all. My mother and he are both entrenched in right-wing extremism,” he added, expressing disappointment over the incident.

On Tuesday night, Kazmierczak, 55, was reportedly the individual seen charging at Omar (D-Minn.) while she addressed the audience at a town hall meeting. During her speech, she criticized Homeland Security Secretary Kristi Noem and advocated for the dismantling of ICE.

Witnesses recall him yelling something unintelligible before brandishing a syringe and dousing Omar with a brown liquid, causing immediate concern over potential harm. It was later identified as apple cider vinegar, mitigating initial fears.

His brother is convinced he struck the Somali American lawmaker because of his deep-rooted bias against the community that has been accused of massive fraud in the state.

“He has had a hatred of the Somali community for probably 20 years,” Kazmierczak’s brother told the Independent.

“There’s a reason I don’t talk to him… He’s got a lot of anger, I have no idea where it comes from. He’s always been that way. In and out of treatment since he was a kid.”

Kazmierczak was grabbed by security and later arrested by Minneapolis Police Department officers and booked into Hennepin County Jail for third-degree assault.

Omar, who continued speaking after Kazmierczak was escorted out, later claimed the disturbing attack was motivated by anger over not enough Somalis being deported — and suggested President Trump is to blame for the assault.

“The man that attacked me was specifically upset that Trump’s order to deport Somalis was not yielding enough deportations of Somalis,” the lawmaker told reporters Wednesday.

“He wanted to come get the person he thought was protecting the Somalis.”

One of Kazmierczak’s neighbors told The Post he’d hinted in a cryptic text days earlier that he might end up leaving the event in handcuffs.

“He said, ‘I’m going to this Omar thing.’ I’m like, Omar what? He said, ‘This town hall thing.’ And he said, ‘I might get arrested,’” Brian Kelley told The Post.

“I didn’t take him seriously. I’m surprised, but not overly surprised,” the neighbor added. “I figured when he said he was going to go to the town hall, he’d stand up and say something stupid. I can’t imagine him assaulting or spraying somebody.”

Kelley described Kazmierczak as a “pretty conservative guy” who “doesn’t like Omar.”

Kazmierczak has been “heavily medicated” since a car wreck damaged his spine, Kelley said, and he has since been diagnosed with Parkinson’s disease.
