Donald Trump Jr. shared a photo on social media of a meal on his father’s plane that included McDonald’s hamburgers and fries, ironic given recent health promises made by his father and future Health Secretary Robert F. Kennedy Jr. The group, including Elon Musk, attended a Mixed Martial Arts event in New York. Kennedy Jr., known for his anti-vaccine stance, had previously criticized Trump’s eating habits, calling the food served on the plane ‘poison.’
