Right-wing youth activist and influencer Charlie Kirk (inset), a major ally of President Donald Trump, has been shot dead in a "political assassination".
Youth activist and influencer Charlie Kirk, a major ally of President Donald Trump, has been shot dead in a “political assassination” that sparked fears of more political violence in an increasingly febrile United States.
Trump confirmed on social media that Kirk, 31, had died from his injuries.
“The Great, and even Legendary, Charlie Kirk, is dead,” Trump wrote on Truth Social.
Kirk was hit while speaking at an event at Utah Valley University.
Video from the scene showed him addressing a large crowd when the sound of a single shot rang out. Kirk appeared to collapse in his chair before the camera swiftly moved and sounds of panic erupted in the audience.
Investigators said they believed the single bullet had come from a campus rooftop, fired by someone dressed in black, in what appeared to be a targeted killing.
The subject for the horrific shooting today that took the life of Charlie Kirk is now in custody. Thank you to the local and state authorities in Utah for your partnership with @fbi.

We will provide updates when able.
A person taken into custody on suspicion of involvement in the shooting has been released, the FBI’s director said hours after announcing the detention.
“The subject in custody has been released after an interrogation by law enforcement. Our investigation continues and we will continue to release information in interest of transparency,” director Kash Patel posted on X.
Illustrating the huge importance of Kirk in Trump’s orbit, the 79-year-old Republican ordered flags on Government buildings to be lowered to half-staff until Sunday. American flags at the White House were lowered shortly after the President’s order.
“No one understood or had the Heart of the Youth in the United States of America better than Charlie. He was loved and admired by ALL, especially me, and now, he is no longer with us,” Trump wrote.
Utah Governor Spencer Cox told reporters Kirk’s killing was “a tragic day for our nation”.
“I want to be clear that this is a political assassination,” he said.
Cox, a Republican, appealed for Americans to take a step back from such violence as the nation readies to mark a milestone anniversary of its 1776 founding.
“We just need every single person in this country to think about where we are and where we want to be, to ask ourselves: is this what 250 years has wrought on us?”
Former Utah congressman Jason Chaffetz, who was at the rally, told Fox News the shooting had happened while Kirk was doing a question-and-answer session with the crowd.
“First question was about religion. He went on for about 15-20, minutes. Second question, interestingly, was about transgender shooters, mass shooters, and in the midst of that, the shot rang out,” a visibly shaken Chaffetz told the network.

“As soon as that shot went out, he fell back,” he said. “Everybody hit the deck... a lot of people started screaming, and then everybody started running.”
Kirk had an outsized influence in US politics, helping the rise of Trump’s support among younger voters – one of the key factors in the Republican’s return to power last year.
With natural showmanship skills, Kirk co-founded Turning Point USA in 2012 to drive conservative viewpoints among young people, turning him into the go-to spokesman on television networks and at conferences for the youthful hard-right.
He used his enormous audiences on Instagram and YouTube to build support for anti-immigration policies, outspoken Christianity and gun ownership, and to spread viral, carefully edited clips of his back-and-forths during debates at his many campus events.
His presence on campuses was seen on the right as a welcome contrast to widespread liberal viewpoints in higher education, but has sparked often fierce opposition.
News of the shooting provoked horror across the political spectrum.
“Dear God, protect Charlie in his darkest hour,” Vice-President JD Vance posted on social media, alongside a picture of the two men and the President’s son, Donald Trump jnr.
Right-wing media figure Tomi Lahren called Kirk “visionary”.
Figures on the left also condemned the attack and urged calm.
“There is no place in our country for this kind of violence. It must end now,” former President Joe Biden wrote on X.
California Governor Gavin Newsom – a frequent foil for right-wing figures like Kirk – called the attack “disgusting, vile, and reprehensible”, while Biden’s Vice-President Kamala Harris said “political violence has no place in America”.
Former Congresswoman Gabrielle Giffords – a Democrat who survived an assassination attempt herself – said she was “horrified” by the attack.
“Democratic societies will always have political disagreements, but we must never allow America to become a country that confronts those disagreements with violence,” Giffords said.
