Randy Zelin: US trial attorney on Donald Trump telling his base he expects to be arrested tomorrow - Heather du Plessis-Allan Drive

Donald Trump is riling up his base by saying he'll be arrested tomorrow.

It's believed the former US President is talking about the years-long investigation into a hush money scheme involving adult film actress Stormy Daniels.

US trial attorney Randy Zelin says this is just fanfare from Trump.

He says former presidents are offered the opportunity to "surrender".

"You walk into the courthouse, you walk into the precinct under your own power, you are fingerprinted, your picture taken and you will either walk over to the court or you're given another date to come back."
