First time US president and vice president to speak at service for non-elected citizen
By David Blevins, US correspondent
Donald Trump's cabinet has exchanged Washington DC for Glendale, Arizona in an unprecedented tribute to Charlie Kirk.
Never in living memory have a serving president and vice president both spoken at the memorial service of a non-elected US citizen.
The order of service is a who's who of US politics – secretary of state Marco Rubio, secretary of war Pete Hegseth and secretary of health Robert F Kennedy junior are all scheduled to address the congregation.
The memorial to the assassinated conservative activist is a combination of remembrance and rally-cry for the current administration.
Charlie Kirk's Turning Point organisation is credited with securing 46% of the youth vote for Donald Trump last year, an increase of 7% since 2020.
His widow Erika, who will also speak at the event, has vowed to continue his mission, and the administration will want to mobilise that youth vote ahead of next year's mid-term elections.
