Donald Trump is preparing for his arrest this week due to his indictment over a payment to porn star Stormy Daniels.

The former US president will fly to New York tomorrow where he'll be finger printed and have a mug shot taken.

US correspondent Richard Arnold says Trump's set to fly back to his Mar-a-Lago home for a campaign speech the very next day.

He says that the arrest's done nothing to dampen his popularity amongst diehards.

Arnold says Trump's support's surged, leaving Republican rival Ron DeSantis in the dust.
