Federal prosecutors charge man accused of spraying Rep Ilhan Omar at town hall

Man arrested after spraying Rep. Omar with unknown liquid at town hall

Fox News chief congressional correspondent Chad Pergram joins ‘America’s Newsroom’ to report on the incident targeting Rep. Ilhan Omar, D-Minn., during a town hall in Minneapolis.

A federal criminal charge has been filed against the suspect accused of spraying a liquid on Rep. Ilhan Omar, D-Minn., during a town hall event this week.

Anthony James Kazmierczak, 55, "forcibly assaulted, opposed, impeded, intimidated, and interfered with United States Representative Ilhan Omar," says a criminal complaint filed in the U.S. District Court for the District of Minnesota and obtained by Fox News. The charge was filed by the Justice Department in Minnesota and assigned to Magistrate Judge Dulce J. Foster.

Right before the attack, Omar called for the resignation or impeachment of Homeland Security (DHS) Secretary Kristi Noem, following multiple fatal shootings involving federal immigration enforcement agents in Minneapolis.

Kazmierczak, who was previously convicted of two DUIs, was charged at the state level with third-degree assault and was booked into the Hennepin County Jail.

Witnesses could be heard commenting on the foul odor of the substance, which was later identified by a hazmat team as apple cider vinegar, Alpha News reported.

Omar's office issued a statement after the attack, noting the substance was sprayed with a syringe.
