President Donald Trump and other prominent American political figures are heading to Arizona to speak at a memorial for Charlie Kirk, the 31-year-old conservative activist who was killed two weeks ago.
The event, organised by Turning Point USA (TPUSA), is on Sunday at State Farm Stadium in Glendale and could be attended by more than 100,000 people.
Heightened security is expected, including TSA-level screening, according to TPUSA.
Kirk, who co-founded Turning Point USA when he was 18, was shot at a speaking event on a Utah university campus on 10 September, reigniting concerns about political violence in the US.
A polarising figure, differing perspectives about his legacy and possible motives for the shooting have exacerbated deep divisions in the US.
In addition to Trump, those expected to speak at the service include Kirk's widow, Erika, who took over his role as TPUSA CEO; Vice President JD Vance; the president's eldest son, Donald Trump Jr; right-wing political commentator Tucker Carlson; homeland security adviser and White House deputy chief of staff for policy Stephen Miller.
Public shootings in the US are typically met with calls for calm, prayer, and unity, but the Trump administration has framed Kirk's death in the context of a broader fight against the radical left, causing concerns over civil liberties.
Doors open at 08:00 local time (16:00 BST), with the official program set to start at 11:00 (19:00 BST). The dress code is Sunday best - red, white, or blue.
The stadium can hold just over 63,000 people, with TPUSA stating entry will be on a first come, first served basis. A 20,000 capacity stadium has been designated as an overflow area.
The memorial will also be live-streamed on Charlie Kirk's Rumble account, according to TPUSA.
Recent security assessments indicate the service has the same high-profile designation as major events like the Super Bowl. This follows incidents where a person impersonating law enforcement was apprehended near the venue.
Tensions are high following Kirk's death, especially with initial reports suggesting the alleged shooter held leftist views. The exact motive remains under investigation.
