A memorial service for slain conservative commentator Charlie Kirk has begun in Arizona.
Mr Kirk was shot dead during a speaking event at a Utah university.
Among those expected to address the crowd at State Farm Stadium in Glendale, Arizona, are US President Donald Trump, Vice-President JD Vance, Mr Kirk's widow, Erika, and other prominent figures from American conservative politics.
High-profile guests, including Elon Musk, head of the FBI Kash Patel and US Attorney-General Pam Bondi, attended the service.
Mr Kirk, 31, was a prominent figure within the right of American politics and was widely credited with appealing to younger Americans.
Top officials of the Trump administration spoke at the memorial, including Secretary of State Marco Rubio, Secretary of War Pete Hegseth and Secretary of Health and Human Services Robert Kennedy Jnr.
Mr Rubio described Mr Kirk as being wise beyond his years.
"Charlie Kirk was bold … he actively sought to engage people he disagreed with," he said.
"He made a difference, he mattered and he will matter now more than ever.
"He had a direct impact on young men in this country and I think we will remember him for that."
He sought to push conservative messages through a mix of social media platforms.
Thousands of mourners filled the Arizona stadium for the memorial, after lining up for hours.
Many mourners are wearing American-flag-themed clothes, shirts with pictures of Mr Kirk and MAGA merchandise.
Tyler Robinson, 22, has been charged with aggravated murder in relation to Mr Kirk's death.
Speakers, including evangelical Christians, conservative heavyweights and members of Turning Point, the organisation Mr Kirk founded, paid tribute to the right-wing activist.
Conservative commentator Tucker Carlson, who interviewed Mr Kirk multiple times on TV, paid tribute to Mr Kirk's politics and Christianity.
A video showing a combination of some of Mr Kirk's appearances and comments about him was played on the big screens at the service.
Earlier on Sunday, Prime Minister Anthony Albanese said the day was a "very sad occasion for many Americans and, indeed, people who followed Charlie Kirk right around the world".
"The memorial is being held in Arizona and our thoughts are with all those who love Charlie and his family," he told reporters in New York City.
"There's no place for political violence here or anywhere else in the world. This is a tragedy and our thoughts are with all those who will be grieving today."
