As the US Presidential race continues to hot up, the Trump family are under closer scrutiny than ever – not least the eldest son of the family Donald Trump Jr., who has earned a lot of money through public appearances. It isn’t tecnically a violation of the law as Trump Jr. doesn’t work for the White House, but his large fees – $100,000 (£77k) for one keynote at the University of North Texas in 2017 for example – have raised eyebrows. Last year he was met with student protests at the University of Florida, after $50,000 (£38k) was spent on a 48-minute address by the president’s son. Half of the allotted time was filled by his girlfriend, Kimberley Guilfoyle, a senior advisor to President Trump.
