A public memorial service for conservative activist Charlie Kirk, who was killed on Sept. 10 while speaking on a college campus, is being held Sunday in Glendale, Arizona.
Tens of thousands of people are expected to attend the service at State Farm Stadium, including President Donald Trump, Vice President JD Vance and top administration officials.
Trump said he will deliver remarks at the service. The president previously said he would posthumously award Kirk the Presidential Medal of Freedom, the nation's highest civilian honor.
