Charlie Kirk‘s fans are expected to come out in the thousands to remember his life and legacy … with a memorial event scheduled in about a week’s time.

Turning Point USA announced an event titled “Building A Legacy: Remembering Charlie Kirk” will take place on Sunday, September 21 at State Farm Stadium in Glendale, Arizona.

The Arizona Cardinals play in the stadium — they play on the road in San Francisco next week — and, the official capacity of State Farm Stadium is 63,400.

Sources with knowledge tell TMZ … despite many referring to this as a “funeral,” it is not — it’s a memorial event, an important distinction.

President Donald Trump said shortly after Charlie died that he plans to attend Charlie’s funeral … unclear if he meant this memorial event or if the prez will be invited to a smaller, more intimate funeral, too — but we are told Trump will be in attendance at the stadium.

As you know … Kirk was shot on the Utah Valley University campus Wednesday. He was rushed to the hospital, where he was ultimately pronounced dead. Tyler Robinson — a 22-year-old man — was arrested and booked on an aggravated murder charge — among others — in connection with the shooting.

Fans and friends of Charlie’s rushed to honor him with tributes … with the New York Yankees holding a moment of silence for him — while his pals in Congress are asking for a statue of him to be placed in the United States Capitol Building.

His wife, Erika Kirk, addressed the nation via Turning Point USA’s website last night … and, she promised to ensure Charlie’s legacy continues to live on.

Kirk is survived by Erika and his two children. He was 31 years old.
