Kirk, 31, was addressing the open-air crowd with some 3,000 people when a single shot rang out, striking the Turning Point USA cofounder in the neck. Within hours, Trump announced Kirk's death on Truth Social. Trump on Thursday said he would posthumously award Kirk the Presidential Medal of Freedom.

Authorities implored the public to help in their search for the shooter who killed conservative activist Charlie Kirk at a college event in Utah.

"I think, with a high degree of certainty, we have him in custody," President Trump told "Fox & Friends" on Friday morning.

Authorities said a "high-powered, bolt-action rifle" was recovered in a wooded area near the university where Charlie Kirk was shot on Wednesday.

President Donald Trump and his cabinet led calls for prayers for conservative activist Charlie Kirk after he was shot at an event at Utah Valley University on Wednesday. “We must all pray for Charlie Kirk, who has been shot,” Trump wrote on Truth Social moments after the shooting was confirmed. “A great guy from top to bottom. GOD BLESS HIM!”
