Conservative activist and Turning Point USA co-founder Charlie Kirk died Wednesday after he was shot at an event at Utah Valley University. He was speaking to a large crowd at an outdoor "Prove Me Wrong" debate, where he invites students to challenge his political and cultural views. 

Authorities posted images Thursday of a "person of interest" and asked the public for help in identifying the individual. The Utah public safety commissioner said law enforcement has "good video footage" of the suspect, who has not yet been identified. Law enforcement officials also said the weapon used has been recovered and described it as a "high-powered, bolt-action rifle." 

Vice President JD Vance and second lady Usha Vance will fly with Kirk's body on Air Force Two to his hometown in Phoenix, Arizona, according to officials.

President Trump paid tribute to Kirk, and elected officials on both sides of the aisle swiftly condemned the attack and denounced acts of political violence.
