Robert F Kennedy Jr was pictured eating McDonald’s on Donald Trump’s private plane as they made their way to watch the UFC in New York on Saturday night.

RFK Jr, who Mr Trump has tapped as America’s next health secretary, struck an awkward pose as he sat with his McDonald’s burger, fries and Coca Cola – the president-elect’s favourite meal.

He was joined by Elon Musk as Mr Trump was given a hero’s welcome during his first appearance at the UFC since winning the election earlier this month.

RFK Jr was highly critical of the modern diet during the election campaign, vowing to ‘Make America Healthy Again’, and even described Mr Trump’s diet as “really bad”.
