Australia’s richest person, Gina Rinehart, has been spotted at Donald Trump’s Halloween party at his Mar-a-Lago resort.

The mining billionaire, who has never shied from publicly praising the controversial two-time US president, was seen speaking at Trump’s ear while he read a piece of paper in a social media post at the lavish affair at the weekend, as first reported by the Nine newspapers.

The image, posted by the former US attorney for the District of Columbia, Jeanine Pirro, also included the US secretary of state, Marco Rubio.
