Charlie Kirk, the 31-year-old founder and chief executive of Turning Point USA and a high-profile conservative organizer and commentator, was fatally shot Wednesday while speaking at an event on the Utah Valley University campus, authorities and allies said.

Kirk was struck during a noon appearance beneath a white canopy in a terraced courtyard as he addressed a crowd estimated at more than 3,000 people for an event billed as "The American Comeback" and "Prove Me Wrong." He was transported to a nearby hospital in critical condition and later pronounced dead. He is survived by his wife, Erika, and two young children.

Witnesses described a chaotic scene after a single gunshot rang out. Authorities said the shooter appeared to fire from a distant rooftop and then fled; law enforcement launched an immediate search and set up roadblocks around the campus in Orem, Utah. Late Wednesday night the suspected gunman remained at large, and police helicopters were reported circling the area as investigators continued efforts to identify and apprehend the shooter.

Students and others in the crowd said security at the event had been light. Utah Valley University assigned six university police officers to the appearance and supplemented them with private security, but there were no metal detectors or bag checks, several attendees told reporters. Videos circulating on social media showed Kirk tossing red hats to attendees and answering audience questions moments before the shot.

The attack drew swift and widespread condemnation across the political spectrum and renewed debate about rising political violence in the United States. President Donald Trump, who had been an ally of Kirk, posted that Kirk was a "great guy" and urged prayers for his family. Vice President JD Vance, a close friend and political ally, posted a personal remembrance on X, praising Kirk's faith and organizational role in the conservative movement and writing, "You ran a good race, my friend. We've got it from here."

Illinois Gov. J.B. Pritzker, a Democrat, condemned the shooting while also faulting inflammatory rhetoric nationally, saying that political violence has been "ratcheting up" and adding, "I think the president's rhetoric often foments it." Republican critics called on leaders to focus on condemning the violence without attributing blame before the investigation concluded.

Lawmakers and public figures who have themselves survived political attacks or lost relatives to violence said the shooting was a stark reminder of the dangers of polarized public life. Former Rep. Gabby Giffords, who survived a 2011 assassination attempt, called the shooting "reprehensible," and former House Majority Leader Steve Scalise, who was wounded in a 2017 congressional baseball practice attack, urged prayers for Kirk. Others noted a string of politically motivated attacks in recent months and years and called for measures to reduce violence.

Kirk rose to national prominence as the founder of Turning Point USA, an organization that mobilized conservative students and held high-profile campus events. He became a familiar figure at rallies and on conservative media, blending political argument with religious testimony; he often spoke publicly about his Christian faith. Turning Point events frequently drew protests and heated exchanges on campuses.

At the Utah event, attendees said Kirk fielded questions from students and supporters about gun violence and other cultural issues. Video and witness accounts show Kirk responding to an audience question moments before the shot. Several people described frantic scenes after the gunfire — crowds stampeding, people leaping over benches and sheltering in nearby buildings. Some attendees reported leaving behind phones, keys and personal items in the panic.

Local and national officials urged the public to avoid speculation while investigators worked to determine a motive. Authorities said they had collected video and were canvassing the area for leads. University officials reiterated their commitment to free expression while grappling with the aftermath of the attack and the trauma inflicted on the campus community.

The shooting set off a wave of online reactions beyond U.S. officials. International commentary included polarizing posts from activists and outlets that drew condemnation for appearing to celebrate or trivialize the killing. An Australian commentator and several media outlets published posts that critics called insensitive; some of those posts were removed or amended after public backlash.

Kirk's death comes amid broader concerns about political violence in the United States, with past incidents cited by public officials as signs of an escalating trend. Those incidents include the murder of Minnesota lawmakers earlier this year, the 2022 attack on the husband of then-House Speaker Nancy Pelosi, and failed or attempted attacks on several public figures. Commentators and politicians called Wednesday's shooting a reminder of the stakes of heated political rhetoric and the need for restraint.

A small vigil and tributes to Kirk sprang up near Turning Point's Phoenix headquarters and on social media as allies and critics alike grappled with the news. Investigators asked anyone with video or information related to the shooting to come forward as the manhunt and inquiry continued.

Authorities provided no immediate public details about a possible suspect or motive and urged patience as forensic and video evidence were reviewed. Utah state and local officials said they were coordinating with federal authorities as part of the investigation. The university said counseling and support services were being made available to students, faculty and staff affected by the shooting.

Kirk's prominence in conservative politics made his campus appearances both a draw and a flashpoint. He leaves behind a national profile built on organizing students, hosting a popular podcast and aligning closely with key figures in the Republican movement. As investigators continue their search for the shooter, political leaders called for calm, condemned violence, and urged due process while memorials and public discussion of the attack unfolded across the country.
