As a memorial is held this weekend for Charlie Kirk, who espoused views that both rallied fierce support and drew forceful criticism, his murder has been a catalyst for a national dialogue about political violence and free speech.

Glendale

A memorial service is being held in Glendale, Arizona, to honor the life of conservative activist Charlie Kirk, who was assassinated while speaking at Utah Valley University. Kirk, a prominent ally of former President Donald Trump, was 31 years old at the time of his death. The event is expected to draw over 100,000 attendees, including President Trump and Vice President J.D. Vance, with security measures comparable to those used at major sporting events.

Authorities have identified 22-year-old Tyler Robinson as the suspect in Kirk's killing, with prosecutors seeking the death penalty. Kirk's death has sparked a national conversation about political violence and free speech, with leaders across the political spectrum, including former President Barack Obama, urging for civil discourse and nonviolence. A growing memorial outside Kirk's nonprofit, Turning Point USA, reflects the widespread impact of his death.

Charlie Kirk's memorial, and the wake of political violence

A memorial service will be held later today in Glendale, Arizona, to remember the life of activist Charlie Kirk. Our Robert Costa has been following Kirk's murder from the first. Songs and calls for peace united attendees at Utah Valley University Friday night. This past week and a half has reminded me of how fragile life can be. It was 11 days ago in Orem, Utah, where an act of political violence stunned this community and the nation. Oh, my God, go run, run. Conservative activist Charlie Kirk, a close ally of President Donald Trump, was assassinated on campus as he spoke to students. He was 31 years old. I've never seen anybody relate to youth like Charlie, and they related to him. The president and vice president, J.D. Vance, are scheduled to speak at today's public memorial service in Arizona, where Kirk lived with his wife, Erica, and two children. Police say they are expecting more than 100,000 people to attend the event at State Farm Stadium and an overflow arena next door. Security will be as tight as it is for the Super Bowl. Glendale police spokesman Jose Santiago. The only difference here is when you have something like the Super Bowl, we had upwards of two years to plan an event like that. This we had a week to work with. Secret Service is leading security as federal agencies track several threats of unknown credibility, according to a memo obtained by CBS News. This has been a very difficult week in America. The death of Kirk, whose views drew intense support and criticism, has been a catalyst for a national dialogue about political violence and free speech. Our friend Charlie did not pass away in a in a car accident. He was assassinated for standing for his political beliefs. And beyond the House speaker here at the Capitol, so many have spoken out this week about the aftermath of the Kirk assassination, including former President Barack Obama. The premise of our of our democratic system is, is that we have to be able to disagree. And have sometimes really contentious debates without resort to violence. In Utah, 22 year old suspect Tyler Robinson made his first court appearance Tuesday virtually. Prosecutors say they will seek the death penalty. Back in Phoenix, the makeshift memorial outside Kirk's nonprofit, Turning Point USA, continues to grow as people look on there and across the country and search for answers.
