Conservative activist Charlie Kirk is set to be honored Sunday at a massive public memorial service that will include speeches from President Donald Trump and Vice President JD Vance at State Farm Stadium in Glendale, Arizona.

The memorial service for Kirk, who was assassinated on Sept. 10 during the first stop of Turning Point USA’s “The American Comeback Tour” at Utah Valley University, is expected to draw tens of thousands of visitors, including senior White House officials and young conservatives influenced by the late 31-year-old.

Trump said he would attend Sunday’s memorial in Arizona to honor Kirk, though he admitted “there are no words to really describe what happened.”

“He had just an army of young people,” Trump said, describing Kirk’s influence on young conservatives. “They loved him so much. I mean, they’re devastated right now. Everybody is devastated.”

Other scheduled speakers include Health and Human Services Secretary Robert F. Kennedy Jr., Secretary of War Pete Hegseth, Director of National Intelligence Tulsi Gabbard, Donald Trump Jr., Tucker Carlson, White House advisor Stephen Miller and Sergio Gor.

The memorial will be broadcast on Fox News Channel and streamed on Fox News Digital.
