The death of Turning Point USA founder Charlie Kirk, a prominent conservative activist, led to an outpouring of support throughout the sports world on Wednesday and Thursday.

Mr. Kirk, 31, was fatally shot while hosting an event at Utah Valley University on Wednesday, authorities confirmed. A suspect was still at large on Thursday morning, and investigators had not publicly announced a potential motive, though the shooting was widely believed to be associated with the commentator’s conservative beliefs.

“Charlie Kirk, a name synonymous with having the courage to speak what you believe and seek/welcome conversations with those whom you disagree with,” Pat McAfee, a former NFL punter known for his brash podcast, wrote on X. “I’m not a political person but I am a proud American citizen and today was startling, saddening, and maddening all at the same time.”

Mr. Kirk was widely credited with voicing conservative perspectives on college campuses and social media. His online videos drew millions of views.

“Praying for him and his family,” Jaxson Dart, a rookie quarterback for the New York Giants, wrote on social media. “Charlie did great things for our country!! Political Violence NEEDS TO STOP!! Pray for our country man. This is disgusting and Sad!!!”

President Trump ordered flags to fly at half-staff from Thursday through Sunday in Mr. Kirk’s honor.

“Above all else, Charlie was a follower of Jesus, a husband, and a dad,” former NFL quarterback Tim Tebow wrote on X. “He was a man of passion, courage, and devotion to making an eternal impact.”
