Kyle Howard Rittenhouse was born on January 3, 2003, in Antioch, Illinois, and became a nationally recognized figure following a fatal shooting incident in Kenosha, Wisconsin, in August 2020. At the time, he was a 17-year-old teenager who traveled to Kenosha amid protests and civil unrest that erupted after the police shooting of Jacob Blake. Rittenhouse joined a group of armed individuals who stated they were protecting local businesses from rioting and destruction. During a series of confrontations that night, Rittenhouse fatally shot two men, Joseph Rosenbaum and Anthony Huber, and wounded a third man, Gaige Grosskreutz. The circumstances of the shootings, captured on video and widely circulated online, immediately thrust him into the center of a national debate over gun rights, self-defense laws, and racial justice protests.

Rittenhouse was charged by Kenosha County prosecutors with multiple counts, including first-degree intentional homicide, reckless endangerment, and illegal possession of a dangerous weapon by a person under 18. His trial, which began in November 2021, drew intense media scrutiny and became a flashpoint in American political discourse. The defense argued that Rittenhouse acted in self-defense, maintaining that each of the men he shot had either attempted to grab his firearm or pointed a weapon at him. On November 19, 2021, a jury acquitted Rittenhouse on all charges, finding that he had acted in self-defense under Wisconsin law. The verdict sparked widespread reactions across the country, with supporters celebrating the outcome as a vindication of the right to self-defense and critics expressing outrage over the deaths and the broader implications of the case.

Following his acquittal, Rittenhouse became a prominent figure in conservative circles. He met with then-President Donald Trump at Mar-a-Lago and conducted a high-profile interview with political commentator Tucker Carlson. He also made guest appearances at events hosted by Turning Point USA, a conservative nonprofit organization, and was offered internships by several Republican politicians. His image was widely circulated and used in political messaging by both supporters and critics, becoming an internet meme and appearing on various commercial products. Several proposed laws were named after him, and he even appeared in a video game.

In the years since the trial, Rittenhouse has pursued a public-facing career aligned with conservative and gun rights advocacy. He started a YouTube channel focused on gun rights and has raised money for unspecified defamation lawsuits against media companies. As of early 2023, two civil lawsuits against him remained pending. His life and legal case continue to be subjects of intense public debate, reflecting broader divisions in American society over firearms, self-defense, and the intersection of justice and politics.
