Donald Trump said on Friday he hoped Charlie Kirk’s killer would be executed as a two-day manhunt across the United States for the assassin came to an end.

Tyler Robinson, 22, was unmasked as the suspect after he was turned in by his father, Matt, who recognised him from images released by the FBI.

Mr Robinson then extracted a confession from his son, law enforcement sources said.

Mr Robinson contacted a clergyman friend who informed the Utah County Sheriff’s Office, and his son was arrested by US Marshals at 10pm local time.

Mr Trump revealed news of the arrest during a live appearance on breakfast TV, telling Fox News: ‘The father said, “we’ve got to go in.” He’s going to be found guilty I imagine. And I hope he gets the death penalty.
