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.
The service at State Farm Stadium in Glendale, Arizona, was attended by high-profile guests including US President Donald Trump, Vice-President JD Vance, Mr Kirk's widow, Erika, former DOGE head Elon Musk and other prominent figures from American conservative politics.
Mr Kirk, 31, was a prominent figure within the right of American politics and was widely credited with appealing to younger Americans.
His widow, Erika Kirk, said her husband's death had sparked a "revival".
"On the afternoon of September 10, I had to do the unthinkable: look at my murdered husband's body," she said.
"I felt shock, I felt awe and a level of heartache that I didn't even know existed … but there was something else too — even in death, I could see the man that I loved.
"I also saw on his lips, a faint smile — it revealed to me a great mercy in this tragedy: Charlie didn't suffer."
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 F 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.
Donald Trump Jnr used his speech to rally the MAGA faithful.
"We won't back down, we won't be intimidated, we will not be silenced," the president's son said.
"We are all Charlie.
"Will you surrender? Will you back down? Will you give up in fear?
"Charlie's message, like Christ's, was an invitation: if you believe in faith, if you believe in family, this movement is your home."
Tyler Robinson, 22, has been charged with aggravated murder in relation to Mr Kirk's death.
A range of 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."
