Charlie Kirk's memorial service at State Farm Stadium was attended by tens of thousands of people in Glendale, Arizona, Sunday.
The big picture: Erika Kirk, the conservative activist's widow who replaced him as CEO of Turning Point USA, said at the State Farm Stadium service that "now his mission is my mission." She said she forgives the suspect in her husband's killing.

A tearful Erika Kirk said during her tribute she "saw on his lips the faintest smile" on her husband's lifeless body. "That told me something important. It revealed to me a great mercy from God from this tragedy. When I saw that, it told me Charlie didn't suffer." Photo: Mandel Ngan/AFP via Getty Images

Erika Kirk vowed to expand Turning Point USA. "Campus events will continue and we will continue to hold debates and dialogue," she said. Her late husband was holding one such debate at Utah Valley University when he was fatally shot earlier this month. Photo: Joe Raedle/Getty Images

After Erika Kirk urged people to love their enemies, Trump railed against the "radical left" and said: "I hate my opponent and I don't want the best for them. Sorry, Erika." Photo: Joe Raedle/Getty Images
