Anthony Kazmierczak, 55, was arrested following the incident and has been charged with third-degree assault.
Despite the attack, Omar remained on stage, stating that "these f***ing ***holes are not going to get away with it" and emphasizing her resilience.
The suspect, described by a neighbor as "pretty conservative" and disliking Omar, had a history of critical political social media posts, including against the Biden administration.
The incident occurred hours after Donald Trump had publicly criticized Omar, questioning her patriotism and origin, a frequent theme in his speeches.
