Good evening. I'm Ali Rogan. John Yang is away. A massive crowd gathered today in Arizona for the memorial service of Charlie Kirk, the conservative political activist who was gunned down 11 days ago.

Tens of thousands of people are in attendance inside a football stadium with a heavy security presence. The memorial called Building a Legacy is mixing music and prayer with a call to action.

Among the attendees and speakers are President Trump, Vice President Vance, and many members of the administration.

In the wake of Kirk's assassination, a debate has waged over polarization,

political violence, and the limits of free speech. Colleagues of Kirk's assassination, a debate has waged over polarization, political violence, and the limits of free speech.

Colleagues of Kirk's took different tones in their remarks.

We will miss your words of wisdom. Your high-pitched laugh was kind of awkward.

And the way your voice would always soften when you spoke to Erica and your children.

Eleven days ago, my friend was martyred for using his voice to engage in peaceful dialogue.

Charlie's assassin thought that he could steal and silence his voice by putting a bullet

in his neck. For more on Charlie Kirk's legacy, we turn to Kyle Spencer, a journalist, and the

author of a book about the conservative youth movement in the U.S. called Raising Them Right. Kyle,

thank you so much for joining us. This memorial service is ongoing.

We still have yet to hear from several major figures, including President Trump and Charlie Kirk's

widow, Erica. But what is your impression of the memorial service as it's gone on today?

So thank you so much for having me. I'm very glad to be here. I would say first of all,

that it is always very sad to witness a moment like this. And I think the first thing that struck me

was how many people have come out to celebrate Charlie Kirk. And then also to see so many of the

people that worked closely with Charlie Kirk's telling personal

anecdotes about how good he was to them.

Charlie, I spent a lot of time with Charlie and the people who worked with him.

Everybody who worked with Charlie felt very, very bonded to him.
