Another person's been arrested for an alleged assassination attempt on Donald Trump.

The former President has been speaking at Coachella, California, three weeks out from election day.

Las Vegas man Vem Miller was intercepted by police at a checkpoint about 800 metres from the rally.

US correspondent Richard Arnold told Mike Hosking he was carrying a shotgun, a loaded handgun, and a high-capacity magazine.

“This bloke was 49, we don’t have a lot of detail about him as yet, but this follows of course the two assassination bids on Trump.”
