Memorial to be held for Charlie Kirk in Arizona

(NewsNation) — A memorial for assassinated conservative activist Charlie Kirk will be held on Sept. 21, a person familiar with the details told NewsNation.  

Turning Point USA, Kirk's conservative organization, will hold the memorial at State Farm Stadium outside Phoenix, where the Arizona Cardinals play.

Doors will open at 8 a.m. with the program set to begin at 11 a.m. local time, according to Turning Point USA. The organization is inviting those hoping to attend to register ahead of time, calling the memorial a "first come, first serve" event. Admission is free, according to the registration form, with additional details provided on Saturday, Sept. 20.

Kirk's casket arrived Thursday in his home state aboard Air Force Two, accompanied by Vice President JD Vance. Funeral details have not been released.

There will be private events in the days prior, including a prayer vigil in Washington, D.C. on Sunday.

Members of Congress and other political figures will hold a memorial service and prayer vigil this day at 6 p.m. ET near the White House and United States Capitol.

"This service will be a unifying event focused on prayer, mourning, and celebrating the life, legacy, and memory of Charlie Kirk — a national treasure whose life was cut far too short," a press release from Arizona state Sen. Jack Hoffman, a Republican, said.

Kirk, the 31-year-old founder of political organization Turning Point USA, was fatally shot at a Utah Valley University event on Sept. 10. A suspect, Tyler Robinson, 22, was arrested two days later.

"The President was clear: the perpetrator of this horrific act will pay for what they did. They will face the full wrath of the American justice system. And any other left-wing whack jobs who engage in targeted political violence like the tragic assassination of Charlie Kirk will be held accountable to the fullest extent of the law," Abigail Jackson, a White House spokesperson, told NewsNation.
