The man who squirted an unknown substance on Democratic U.S. Rep. Ilhan Omar at a town hall in Minneapolis has a criminal history and made online posts supportive of President Donald Trump. Minnesota court records show 55-year-old Anthony Kazmierczak was convicted of felony auto theft in 1989 and has multiple arrests for driving under the influence. Police say Kazmierczak used a syringe to squirt an unknown liquid at Omar on Tuesday. He was immediately tackled and is charged with third-degree assault. Omar said she is OK and continued speaking. In social media posts, Kazmierczak criticized Democrats, calling them “angry and liars.”
