US President Donald Trump has expressed hope that the alleged k!ller of Charlie Kirk will face the de@th penalty.
Tyler Robinson was arrested by the FBI following a two-day manhunt in Utah.
The 22-year-old was apprehended after his father, Matt, turned him in.
According to law enforcement, Mr Robinson extracted a confession from his son.
Matt later contacted a clergyman friend who informed the Utah County Sheriff’s Office, and his son was arrested by US Marshals at 10 pm local time.
“He’s going to be found guilty I imagine. And I hope he gets the de@th penalty,” Trump said during a live appearance on Fox TV.
“Charlie Kirk was the finest person. He didn’t deserve this. He worked so hard, and so well. Everybody liked him.”
Mr Kirk, 31, a father of two, was shot de@d by a gunman who used a hunting rifle to fire a single shot across the campus of Utah Valley University on Wednesday.
