Anthony Kazmierczak faces federal assault charges after he appeared to spray the congresswoman with liquid from a syringe

The Department of Justice has filed federal charges against the man accused of attacking Democratic congresswoman Ilhan Omar at a town hall in Minneapolis on Tuesday. In newly filed court documents, a “close associate” told investigators that the alleged attacker previously said that someone “should kill” the Minnesota lawmaker.

Local police arrested and booked Anthony James Kazmierczak, 55, for third-degree assault after he appeared to spray Omar with an acidic-smelling liquid from a syringe as she addressed constituents from a lectern.
