An Orland Park, Illinois, man was arrested Sunday after he got into a violent confrontation with a poll worker, punching them in the face, according to police.
Daniel Schmidt, 24, allegedly walked into the building and passed other voters waiting in line to enter the voting area, Orland Park police said. An election judge told Schmidt to go to the back of the line and called another judge to assist, officials said. Schmidt tried to push past that election judge and was stopped from entering the voting area by the judge and other employees, according to police.
Schmidt then allegedly started yelling profanities and punched the election judge in the face, knocking their glasses off, witnesses told officers.
He also then resisted while being placed under arrest, police said.
He has been charged with two counts of aggravated battery of a victim of at least 60 years old, two counts of aggravated battery in a public place, five misdemeanor counts of resisting arrest and one misdemeanor count of disorderly conduct.

Vice President Kamala Harris continued her Monday swing through Pennsylvania with a rally targeted in large part at Puerto Rican voters in Allentown, a majority-Latino city, where the Harris campaign sees an opportunity to woo voters turned off by the racist joke Tony Hinchcliffe told at former President Donald Trump’s New York rally last month.
When Mayor Matthew Tuerk mentioned Hinchcliffe's "garbage" comment, the crowd at the Muhlenberg College gymnasium booed, and at least two Puerto Rican flags were unfurled.
Rapper Fat Joe, who spoke shortly before Harris, called upon Latino voters to have "pride" and reject Trump.
"They said they needed a Puerto Rican in Allentown, and I was more than honored to come speak to my people," he said.
In her own remarks, the vice president touted her "long-standing commitment to Puerto Rico and her people."
She promised that she would be "a president for all Americans" and added that her campaign has "momentum" in the closing hours of the race.
"It is my pledge to you, if you give me a chance to fight on your behalf as president, there is nothing in the world that will stand in my way," Harris said.

Following a six-hour hearing on Monday, a Philadelphia judge is allowing Elon Musk's America PAC to continue its million-dollar giveaway to registered swing state voters.
Common Pleas Court Judge Angelo Foglietta denied Philadelphia District Attorney Larry Krasner's request for an injunction to stop the giveaway, which has handed out $17 million to voters across the swing states. According to defense attorneys, America PAC plans to announce their 18th and final prize winner tomorrow in Michigan.
