MADISON, Wis.— An Illinois teenager who fatally shot two people and wounded a third amidst sometimes violent summer protests on the streets of Kenosha, Wisconsin, pleaded not guilty on Tuesday to charges including intentional homicide.

Kyle Rittenhouse, 18, entered his plea in a brief hearing conducted by teleconference that came just as Kenosha was bracing for a charging decision in the event that brought Rittenhouse to the city in August — the police shooting of Jacob Blake.

Prosecutors say Rittenhouse, who is white, left his home in Antioch, Illinois, and traveled to Kenosha after learning of a call to protect businesses after Blake, a Black man, was shot seven times in the back Aug. 23 and left paralyzed.

Rittenhouse opened fire with an assault-style rifle during protests two nights later, killing Joseph Rosenbaum and Anthony Huber and wounding Gaige Grosskreutz. Rittenhouse has argued he fired in self-defense. Conservatives have rallied around Rittenhouse, describing him as a patriot who took up arms to protect people and property, and raised enough money to make his $2 million cash bail.

Others see him as a domestic terrorist whose presence with a rifle incited protesters.

The Blake shooting happened three months after George Floyd died while being restrained by police officers in Minneapolis, which also was captured on bystander video and which sparked outrage and protests that spread across the United States and beyond. The galvanized Black Lives Matter movement put a spotlight on inequitable policing and became a fault line in politics, with President Donald Trump criticizing protesters and aggressively pressing a law-and-order message that he sought to capitalize on in Wisconsin and other swing states.

In Kenosha, as the protests that followed damaged businesses in the city of 100,000 near the Wisconsin-Illinois border — authorities ultimately estimated some $50 million in damage — some people answered a call on social media to travel to Kenosha.

Conservatives have rallied to Rittenhouse’s legal defense, arguing that he was a patriot who took up arms to protect people and property. Rittenhouse, who is white, was 17 at the time of the shootings, and charges include illegal possession of a dangerous weapon by someone under age 18.

Gov. Tony Evers Activated 500 National Guard Troops to Help Kenosha Authorities

A pretrial conference for Rittenhouse was set for March 10, with a March 29 trial date, though his attorney Mark Richards indicated he would seek to delay that to allow more time to prepare.

Kenosha County District Attorney Michael Graveley hasn’t publicly announced the timing of a decision on whether to charge Kenosha Police Officer Rusten Sheskey. But the city began moving in recent days to prepare for the event, with some businesses boarding their windows and concrete barricades and oversized metal fencing surrounding the Kenosha County Courthouse. Fearing a repeat of the August protests, the Kenosha Common Council on Monday night unanimously approved an emergency resolution that goes into effect with the announcement and allows the mayor to set curfews.

Meanwhile, Gov. Tony Evers activated 500 National Guard troops to help Kenosha authorities when the decision is announced.

“Our members of the National Guard will be on hand to support local first responders, ensure Kenoshans are able to assemble safely, and to protect critical infrastructure as necessary,” Evers said in a statement.

Blake’s father led a march through the city Monday evening, calling on people to “make noise” and be “heard around the world.”

“(Sheskey) tried to kill my son and could have killed my grandchildren,” Jacob Blake Sr. said during a news conference before the march. “He shot him seven times in his back unjustifiably.”

The family said it’s taken too long for a charging decision, and the precautions suggest that Sheskey won’t be charged.

“What is the National Guard for?” Jacob Blake Sr. said. “They going to deliver mail? Deliver ice cream? What do you think they’re here for?”

Tanya McLean, executive director of the community organization Leaders of Kenosha and a friend of the Blake family, said as Monday evening’s march was kicking off that violence isn’t acceptable.

“No matter what the decision is, we are seeking nonviolence,” she said. “We want everybody to come out, make as much noise as you want, but we don’t want any destruction of property or businesses. We are for nonviolence. Anything else is not acceptable for this community.”
