Based on my research, here is my analysis of the claim:

Reasoning:

• Charlie Kirk, the conservative activist and co-founder of Turning Point USA, was indeed shot and killed on September 10, 2025, while speaking at an event at Utah Valley University in Orem, Utah¹²³. This event is being referred to as the "Utah Valley University Attack" or assassination.
• Multiple authoritative sources including NBC News, WIRED, CNN, NPR, PBS, and The Guardian all confirm the shooting occurred while Kirk was presenting at a campus event⁴⁵⁶¹³.
• The White House issued an official proclamation declaring a "National Day of Remembrance for Charlie Kirk," confirming he was "assassinated in broad daylight in a campus courtyard" on September 10, 2025⁷.
• The suspect was later identified as Tyler Robinson, a 22-year-old who was charged with aggravated murder⁸.
• Kirk was shot in the neck while seated under a tent, and died at Timpanogos Regional Hospital²¹.
