Trump is on the campaign trail as the US mid-term elections are set to take place next month.
The President has been touring around red states, doing back-to-back rallies in Texas and Oklahoma.
US correspondent Richard Arnold says Trump has been urging his base to get out and vote - but his latest campaign ads have raised questions.
"US law prohibits Government funds from being used for political campaigning. Trump, though, claims this is not campaigning, these are simply public service announcements."
